Hydrogen sorption property of Mg in Pd-capped thin film nanoconfined with Fe is investigated. Two methods of depositing the thin films were utilised, i.e., resistive heating method and pulsed laser deposition (PLD) method. In the thinnest Mg film prepared by resistive heating, hydrogen content was observed to be the highest among all samples and the hydrogen desorption temperature is 230 C. Using pulsed laser deposition method, Mg/Fe nanoconfined multilayers are easily prepared. The hydrogen desorption temperature of Mg film with 12 Mg/Fe layers prepared via PLD method was significantly reduced to 155 °C, and the hydrogen storage capacity is improved as compared to the Mg/Fe with only several layers of same overall thickness. This study showed that the desorption temperatures correlate with the film thickness, thinner films react with hydrogen at lower temperatures.

<p>The shape memory effect (SME) in Fe-Mn-Si based alloy is associated with γ ⇄ ε martensitic transformation which is caused by motion of the Shockley partial dislocation. The variants in Fe-Mn-Si based alloy could appear the four orientations according to Shouji-Nishiyama (S-N) relation in the transformation from the austenite phase (A-phase) to the martensite phase (M-phase). It was reported that a single variant formed under the stress induced transformation in the SME and that is the advantage for the shape recovery in the variant selection behaviors. In this study, the variant selection of Fe-Mn-Si based alloy under stress applied is investigated on the basis of crystallography in the SME with Electron Backscatter Diffraction (EBSD). The amount of shape recovery was quantified by means of bending tests and the best recovery ratio was run into 83% for the specimen annealed 873K. The SME is improved by not only the increase of A-phase but also the promotion of the single variant under stress induced transformation. The single variant orientation is selected by the degree of Schmid's factor in the behaviors. In the specimen annealed at 873K, the increase of M-phase concentrates at 0.475 of the Schmid's factor, the single variant orientation, and that suggests the single variant formation.</p>

<p>In this study, four multilayer film samples of polyimide/Mg, polyimide/Mg/Ti, polyimide/Mg/Pd, and polyimide/Mg/Ti/Pd were prepared by pulsed laser deposition and evaluated for hydrogen absorption-desorption properties. Polyimide/Mg and polyimide/Mg/Ti samples did not absorb hydrogen under conditions of 0.8 MPa and 200°C, while polyimide/Mg/Pd and polyimide/Mg/Ti/Pd samples absorbed hydrogen under the same conditions. The polyimide/Mg/Pd and polyimide/Mg/Ti/Pd samples desorbed hydrogen in the temperature ranges of 430-440°C and 140-200°C, respectively. The addition of Pd was necessary for the absorption of hydrogen because Pd promoted the dissociation of molecular hydrogen. The addition of Ti was necessary to decrease the temperature of dehydrogenation. The improved hydrogen absorption-desorption behavior could be caused by the structural change of MgH₂ from bct to fcc and the decreased thermal stability of fcc MgH₂ compared to that of bct MgH₂. The hydrogen storage amount of the polyimide/Mg/Ti/Pd film was determined with pressure-composition-temperature measurements. The sample absorbed 0.42 wt.% hydrogen at 200°C and 2.0 MPa and 0.49 wt.% at 200°C and 10 MPa; hydrogen desorption was incomplete under both conditions. While the hydrogen storage amount of the polyimide/Mg/Ti/Pd film is less than that of pure Mg, it may be increased by omitting the base material of polyimide film.</p>

<p>The shape memory effect of Fe-Ni alloy would be improved with hot dip aluminum coating. There were five types of the specimens, namely #1; just after shape memory treatment (SMT), #2; Al-coated after SMT, #3; Al-coated after SMT and then annealed at 400 degree C, #4; the same but 800 degree C, and #5; annealed at 800 degree C after SMT w/o Al-coated. The shape recovery ratio of the Al-coated specimens (#2) was as much as 20% better than those of w/o Al-coated ones (#1) in V-shaped bending test. All the Al-coated specimens had the intermediate layer at the boundary of Fe-Ni and Al layers. The layer consists of solid solutions of Al dissolved by Fe and Ni with 10 – 20 μm thickness evaluated by microscopic observations. The Vickers hardness was higher than the specimens without Al coating and the specimens with Al coating might have higher yielding stress. The solid-solution layer may store the elastic strain energy during the bending test and then release it for assisting inverse martensite transformation during recovery treatment, thus the recovery may have been strengthened.</p>

Hydrogen storage alloy has a potential material to become one of the most promising candidates as an effective storage system and it has higher safety and storage density than other storage systems. The Mg-based hydrogen storage alloy has the advantage of high hydrogen storage density (7.6 wt% in MgH₂), light weight and low cost, while it needs to improve its slow reaction kinetics and high desorption temperature for practical applications. In this research, we prepared the Mg/Fe multi-layer films with the pulsed laser deposition (PLD) method and studied their hydrogen absorption and desorption properties for the effects of the order of layer and the Ti layer on the surface. The differential scanning calorimetry (DSC) and X-Ray diffraction (XRD) were carried out to characterize the hydrogen desorption temperature and the hydride. As a result, it found that Polyimide/Fe/Mg/Ti multi-layer showed to make the magnesium hydride after hydrogenation and to leave it at 245°C and that is 173°C lower than that of pure magnesium hydride and Polyimide/Mg/Fe/Ti, Polyimide/Fe/Mg and SUS304/Fe/Mg/Ti showed no hydrogen desorption after the hydrogenation.

This study presents a simple interatomic bonding model for disordered A2 and B2 crystal structure. The model consists of an atom-like sphere and eight polar bars attached to its surface. Every bar has a polarity and can only attract a bar of the opposite polarity. Each bar is oriented from the surface of the sphere to a vertex of the cube, of which the sphere is placed in the center. A motif is defined as a combination of polarities on the eight bars, the total of which is 256 although a number of them are identical after rotation and/or inversion. Only 13 motifs classified by point groups are found to be unique by point symmetrical operations. In addition, an A2-like crystal structure is formed by connecting the bars between the models and filling the space. Four bonding patterns are found to configure the space of models with unique motifs according to symmetrical operations between the motifs of the center and neighbor atoms. Each crystal structure includes several kinds of point symmetry, and each shape memory binary alloy (SMBA) can be connected to the motifs on the atomic model via crystal structure and point symmetry. The results reveal the potential structure of the electron population distribution of each element in an SMBA that could be compared with ab initio calculations.

The parent phases of many shape memory alloys (SMAs) are B2 or dis-ordered BCC crystal structures and the order of symmetry of martensite of the SMAs possesses lower symmetry than those of parent. Assumed that a polarity exists in the atomic binds at parent crystals, its motif lets the order to be lower than parent's symmetry. This potential symmetry in each parent crystal will be determined using by the point group theory so that there are 12 unique polarity arrangements. Furthermore, the four neighbor atomic relations are found according to consider polarities with the unique arrangements. This classification applies to the crystal symmetry in martensite of the SMAs.

Mode I and mixed mode loading testing of ABS resin were carried out by using compact tension shear specimens. Two types of ABS resin were examined. The first one (ABS-1) has a butadiene rubber content of 18 wt % in the form of small particles of diameter of about 200 nm. The second one (ABS-2) has the same overall butadiene rubger content but a bimodal particle distribution with diameters of 200 nm and 500 nm. Crack initiation behavior was observed by using a video microscope. The fracture toughness of ABS-2 obtained by mode I testing is larger than that of ABS-1. The fracture angle for both materials under mixed mode loading coincides with the values predicted by the maximum hoop stress criterion. On the contrary, at crack initiation under mixed mode loading, the critical values of K_1 and K_<11> are larger than those estimated by the masimum hoop stress criterion. The increase in the critical values of K_1 and K_<11> under mixed mode loading for ABS-2 is higher than those for ABS-1. The bimodal type distribution of rubber particle size produces better fracture resistance.

The effects of the thickness on the ultraviolet (UV) degradation was investigated for polypropylene (PP) and polycarbonate (PC) using"layering-films exposure test." In this test, the films were stacked up as a layer and exposed to UV-light by the weathermeter. After the exposure, tensile tests were conducted for each film. It was found that the failure strain of PP decreased with the irradiation time irrespective of the mask-film-thickness (MFT) although the tendency of the decrease became weaker for larger value of MFT. On the other hand the failure strain of PC decreased only for MFT=0μm. The fractographic observation by SEM and the chemical analysis by the infrared spectroscopy also confirmed that the UV degradation gradually extended along the thickness direction in PP while it was limited on the irradiated surface layer in PC. The decrease in failure strain was correlated to the irradiation UV energy by taking account of the molecular weight change due to main chain scission.

Silica-particulate-filled epoxide resins are used as encapsulant materials in semiconductor packaging. In the present paper, the effects of moisture absorption on the bending strength and fracture toughness of two types of the epoxide resins containing 70wt.% silica particles have been studied. The bridge indentation method was employed in precracking of specimens. The fracture toughness obtained agreed well with the results of fatigue precracked specimens. The fracture toughness of both resins slightly increased with moisture absorption while the bending strength tended to decrease. Fracture surface observation by scanning laser microscope shows that debonding of the interface between silica and epoxy predominates in the fracture surface of the bonding specimens while cracking of silica particles triggers the fracture of the precracked specimen. It is suggested that differences in bending strength and fracture toughness due to moisture absorption are attributable to differences in the stress triaxiality of the specimens.

It is well known that sunlight induces the ultraviolet (UV) degradation of polymers. This paper describes the effects of UV irradiation on the change of mechanical properties of polypropylene (PP)and polycarbonate (PC) films. After the specimens were exposed to UV light from the fluorescent UV apparatus, some specimens were subjected to a dead load afterwards the exposures. Tensile tests and dynamic viscoelastic mechanical tests were conducted. In addition, infrared spectrum and molecular weight were measured in order to investigate changes in chemical properties. (1) The degradation of mechanical properties due to UV irradiation is divided into two periods, i. e., the degradation-incubation period and degradation-development period. The failure strain does not change in the first period, and gradually decreases with increase of the integrated UV irradiation energy. The applied stress during irradiation has a tendency to accelerate degradation. (2) The temperature during exposure influences degradation considerably when it is greater than the glass transition temperature. (3) The reason for the existence of the incubation period is different for two materials. PP has no active bases originally for light-induced chemical reaction, and thus a certain period is necessary to initiate scission of main chains. On the other hand, PC has active bases but the second conjugation is strong. Therefore a certain number of main chain scissions are required to decrease the failure strain.

A measuring system of strain distribution has been developed to analyze the mechanical behavior of polymer film. The system is composed of the material testing section and the image processing section. A lattice pattern is printed on the specimen surface. During material testing, the deformation of the pattern is recorded by a VCR camera. After the test, some parts of the recorded image data are digitized. Each datum is treated as follows : (I) smoothing to remove naise, (II) selection of the areas including a crosspoint using the image recognition technique based on the neural network, (III) determination of the coordinate of the crosspoint using the minimum square method, (IV) formation of the triangular mesh model, (V) determining the strain distributions of the specimen computed by applying a similer method used in the finite element method. To demonstrate the applicability of the present method, the strain distributions of a dumbbell-type specimen of polyethylene film under tensile testing are determined using this system.

The effects of humidity on the mechanical behavior of polyamide-6 (PA) and cellulose-acetate (CA) were investigated. The specimens were exposed in a chamber at constant temperature and humidity for 4∼16 days, and measurements were made on the variations of weight and tensile properties. In addition infrared analysis was conducted using the attenuated total reflectance attachment with a KRS-5 prism. The result are as follows : ( 1 ) In PA, there exists a linear relationship between the weight change and the maximum stress ; i. e. it becomes heavier and more ductile when it is exposed to high humidity and temperature. The main factor of the weight change is moisture absorption and/or desiccation, and this relationship also holds for the specimens under dry-wet cyclic exposure. ( 2 ) The variation of yield stress of CA is correlated well with its weight change but not with the exposed humidity. IR spectroscopy shows that the weight change of CA occurrs by dispersion of plasticizer as well as by absorption of water. Due to dispersion of plasticizer, the variation of the yield stress under dry-wet cyclic exposure is nonreversible.

This paper presents a method to detemine the distribution of the Younng's modulus of function-ally gradient materials by bending testing. In the method, the measured values of the flexural rigidity, which are obtained by reducing the height of the specimen, are used to inversely analyze the distribution of the modulus across the thickness. The solution is obtained through minimizing the residual between measured data and estimated values. The Davidon-Fletcher-Powell method is employed for minimization of the error. The practical applicability of the method is examined through several examples.

In order to examine the effects of plastic deformation on the stress fields near the bonding edge, an elastic-plastic finite-element analysis was performed on a bimaterial plate. The materials above and below the interface were assumed to be different from each other in Young's modulus and/or yield stress. The plate was subjected to a prescribed uniform axial displacement along the upper boundary. Computation has been performed for various combinations of the material constants, and the following results were obtained. ( 1 )Development of the plastic region is affected not only by the yield stress but also by the elastic modulus. ( 2 )Stress concentration of tensile stress at the edge disappears as yield region extends. ( 3 ) Stress concentration of shear stress at the edge is expressed by |γ|=Kr<SUP>-λ</SUP> under general yielding, and the value of λ takes a constant (λ<SUB>p</SUB>) for a wide range of the deformation stage. ( 4 )The value of λ<SUB>p</SUB> is affected by the ratio of Young's moduli when the ratio of the yield stresses is small.

Environmental degradation due to temperature and humidity has been studied by infrared (IR) spectroscopy on polyethylene (PE), cellulose-acetate (CA) and polycarbonate (PC) films. Specimens were exposed in a vessel at a constant temperature and humidity for 12∼40 days, and tensile tests of the specimens were carried out at room temperature. The weight, the water absorption and the IR-absorption spectra of the specimens were also measured before the exposure and after. Due to the effects of environment, the change of the weight and water absorption occurred for CA, but not for PE and PC. For CA the weight decreased for all exposure conditions while the water absroption increased with humidity. The variation of fracture strain and yield stress was observed for CA, but not for PE and PC. Similarly, only for CA the rate of IR absorption at 745 and 1288 cm<SUP>-1</SUP> decreased with humidity. Linear relationships were found between mechanical properties and the rate of IR absorption.

Low-temperature strength is investigated for polyethylene film used for the observation balloons. Tension tests using danbel-type specimens and crack growth tests using the edge-cracked specimens have been conducted in the temperature range from 20°C to -40°C. The stress-strain curves show little anisotropy, and the yield stress increases as temperature decreases. The maximum load of edge-cracked specimens with the same initial crack length also increases as temperature drops, while elongation at fracture decreases after taking its maximum at 0°C. The crack-tip opening angle at steady-state propagation is a constant independent of the initial crack length and is considered to be a material constant. This value decreases as temperature decreases, and the crack tip becomes sharp at low temperatures. The net section stress at steady-state propagation is also constant under the present experimental conditions. The relationship between the J-integral and crack extension exhibits two straight lines and the value of the J-integral increases as temperature decreases.

We investigate here the load transfer between femur and prosthesis following total hip replacement. First, compression tests using a human cadaveric femur are conducted. Then plaster models for the femur are made from the molds taken from the femur. We believe thet the plaster model femur can allow us to distinguish the minute differences affected from experimental setups. Utilizing the five kinds of cementing materials and the two kinds of prosthesis stems, the effects of the modulus of the cementing materials to the strain distribution on the model femur are examined. Further, a numerical analysis method based on the beam theory is proposed, and the load transfer problems between femur and prosthesis are solved by the Runge-Kutta method. The numerical results obtained are in good agreement with the experimental results, which indicates that the distal load transfer between femur and prosthesis takes place in a manner similar to that between two beams. Both the experimental and analytical results predict that the strain distribution induced on the femur with implanted prosthesis differs from the physiological one considerably; i. e. the strain at the calcar is maximum before implantation whereas the strain at the distal point become dominant after implantation. It may be concluded that the stress shielding can't be avoided as long as the presently available prostheses are utilized.

This study is the influence of elastcrplastic behaviors on low carbon steels by heat treatments. The mechanical tests are conducted and the stress-strain curves obtained for quenching, quenching-tempering, normalizing and as forging specimens. The microstructures were observed for checking effects of the heat treatments. 600 degree quenching-tempering specimen observes carbides. By specific heat treatment the low carbon steel exhibited the stress stable range on the curves but no pseudoelasticity in this case.

In our laboratory, research works on developing the pseudo-elasticity effect (SE) in steel was done in previous years. In 2009, the work focused on the evaluation for the elasto-plasticity of the heat-treated low carbon steel with Si composition. The minor composed(Si, P) low carbon steel was used as samples, which then were heat-treated by means of quenching and quench-tempering. Failure test was conducted for each sample, and elasto-plasticity evaluation done by analyzing the Stress-Strain curve obtained. It is found that Si composition has effect in hardening samples, which can be explained by discussing the Si influence in retardation of cementite precipitation in low carbon steel.

This study examines the rotation transmission performance by the diaphragm shape of diaphragm coupling. The stress state produced in diaphragm of the polyimide material was determined by analyzing the reaction force in each shaft using a finite element method, using allowable lateral misalignment is occurred in coupling between a drive shaft and driven shaft. Next, the stress state was analyzed the same diaphragm shape when angular misalignment occurred. It was examined that diaphragm shape by evaluating rotation transmission performance through lateral misalignment and angular misalignment.

We investigated the improvement in strength and the fracture mode at the fracture of float glass by laminating a film and clarify the strengthening processes. The three-point bending test was conducted with the float glasses laminated with the film in several lengths of the support span and the fracture surfaces of the glass were observed for evaluating the effect of the film lamination. As a result, there are the two kinds of fracture modes, Bending and Hertzian modes, could be expressed by the test. The fracture direction and initiating points were also identified by observing the fracture surface and the mechanism of the fracture modes change and the cause was revealed.
