Updated: 2009-11-03 21:46:48Authors: Bouslama N, Ben Ayed F, Bouaziz J Tricalcium phosphate and synthesized fluorapatite powder were mixed in order to elaborate biphasic composites. The samples were characterized by X-ray diffraction, differential thermal analysis, infrared spectroscopy, scanning electron microscopy and by an analysis using (31)P nuclear magnetic resonance. The sintering of tricalcium phosphate with different percentages of fluorapatite (13.26 wt%; 19.9 wt%; 33.16 wt% and 40 wt%) indicates the evolution of the microstructure, densification and mechanical properties. The Brazilian test was used to measure the rupture strength of the sintered biphasic composites. The mechanical properties increase with the sintering temperature and with the addition of fluorapatite additive. The mechanical resistan...Development of biomedical porous titanium filled with medical polymer by in-situ polymerization of monomer solution infiltrated into pores.
Updated: 2009-11-03 21:46:37In this study, for the fabrication of the abovementioned composite, a versatile process for filling a medical polymer into a porous metallic material has been developed using porous pure titanium (pTi) and polymethylmethacrylate (PMMA). Then, the tensile strength and Young's modulus of pTi filled with PMMA (pTi/PMMA) fabricated using this process are systematically investigated. The tensile strength of pTi can be improved by the PMMA filling. Particularly, the improvement in the tensile strength of pTi pretreated using a silane coupling agent before PMMA filling is greater than that of the non-pretreated pTi because the stress concentration near the pores may be reduced by the improvement in the interfacial adhesiveness between the titanium particles and the PMMA. In contrast, the effect o...Anisotropic swelling and mechanical behavior of composite bacterial cellulose-poly(acrylamide or acrylamide-sodium acrylate) hydrogels.
Updated: 2009-11-03 21:46:19Authors: Buyanov AL, Gofman IV, Revel'skaya LG, Khripunov AK, Tkachenko AA Bacterial cellulose-polyacrylamide (BC-PAAm) composite hydrogels are prepared by synthesis of PAAm networks inside the BC matrices. The behavior of these gels and of the ionic ones obtained via partial hydrolysis of BC-PAAm gels is studied under swelling and compressive deformation conditions. The dependences of the hydrogels' properties on the BC matrix preparation conditions, gel synthesis conditions and the BC content in the hydrogel compositions are studied. Two types of BC gel pellicle are used in the hydrogel synthesis, namely matrix pellicles subjected to pre-pressing (samples of series A) and those not subjected to any mechanical actions before synthesis (series B samples) containing about 99% water. The...Transversely isotropic tensile material properties of skeletal muscle tissue.
Updated: 2009-11-03 21:46:08Authors: Morrow DA, Haut Donahue TL, Odegard GM, Kaufman KR Of the plethora of work performed analyzing skeletal muscle tissue, relatively little has been done in the examination of its passive material properties. Previous studies of the passive properties of skeletal muscle have been primarily performed along the longitudinal material direction. In order to ensure the accuracy of the predictions of computational models of skeletal muscles, a better understanding of the tensile three-dimensional material properties of muscle tissue is necessary. To that end, the purpose of this study was to collect a comprehensive set of tensile stress-strain data from skeletal muscle tissue. Load-deformation data was collected from eighteen extensor digitorum longus muscles, dissected free of aponeur...A composite kidney stone phantom with mechanical properties controllable over the range of human kidney stones.
Updated: 2009-11-03 21:46:05Authors: Simmons WN, Cocks FH, Zhong P, Preminger G A novel composite kidney stone phantom has been developed. This stone phantom is producible with mechanical properties mimicking the range of tensile fracture strength and acoustic properties of human kidney stones and is an inorganic/organic composite material, as are natural kidney stones. Diametral compression testing was used to measure tensile fracture strength, which determines the acoustic comminution behavior of kidney stones. Ultrasound transmission tests were made to characterize the acoustic properties of these stone phantoms. Both the tensile fracture strength (controllable from 1 to approximately 5 MPa) and acoustic properties (C(L) = 2700-4400 m/s and C(T)=1600-2300m/s) of these composite phantom stones match those of a ...Statistical Analysis of Misorientation Distributions From Growth Selection Experiments in Iron–3% Si
Updated: 2009-11-03 15:28:46The frequency of occurrence of differently misoriented grain boundaries in growth selection experiments in silicon–iron was reported by Ibe and Lücke and has been the basis of many texture models. However, this pattern of behaviour bears much similarity to misorientation frequencies calculated from random textures. A comparison of the experimental and computed frequency distribution shows that there are statistically significant differences and therefore that some possibilities for growth selection do exist (Source: Texture, Stress, and Microstructure)Microstructure and Texture of in Situ Heavily Drawn Cu–Nb Composites
Updated: 2009-11-03 15:28:46Heavily cold drawn in situ Cu–Nb composites have been investigated by transmission electron microscopy (TEM) and X-ray analysis. Dislocation density in the copper matrix has been shown to change only slightly in the investigated drawing ratio range because of the development of stage IV of deformation. In Nb filaments dislocation density in the investigated range at first increases with deformation and then drops at the highest drawing ratio. At intermediate deformation niobium grains consist of fine blocks separated by low-angle dislocation boundaries. At drawing, fibre texture develops in both phases, with 〈111〉 and 〈100〉 axis for the copper matrix and 〈110〉 axis for niobium filaments. Besides, niobium filaments acquire ribbon-like form...Effect of Zonal Isolation on the Kinetics of Sintering a Particulate Body
Updated: 2009-11-03 15:28:46This paper describes the so-called meso-scale simulations of sintering a particulate body. Computations were made using 3D structure-imitation computer model of evolution of a powder compact during sintering. It was demonstrated, that in powder bodies the effect of zonal isolation (forming separate groups of particles during sintering) determines features of shrinkage and internal structure of a compact. In case of the diffusion- viscous flow of particles the fact was proved that the zonal isolation is predetermined by ratio of viscosity and free surface energy. It was verified, that there is a critical value of the above ratio with respect to which the balance of internal structure- creating processes is determined.

Updated: 2009-11-03 15:28:46Non-destructive methods to determine the volume fraction of minor texture components with very low reflection intensities are presented. The methods are based on polycrystalline diffraction of hard X-rays from synchrotron sources. By focusing the X-rays and scanning the specimen, it is shown that volume fractions as low as 10-9 can be registered, provided that the crystallographic orientations of such volume elements are far away from any major texture component. Simultaneously, the spatial resolving power is of the order 0.03 μm3. The relevance of such methods for nucleation studies and trace analysis is outlined.

Updated: 2009-11-03 15:28:46Crystallographic orientations of twelve different lead scandium tantalate (PST) ceramics, two lead zirconate titanate ceramics (PZT) and one PZT thin film were investigated by the technique of electron backscatter diffraction (EBSD) in the scanning electron microscope. The PST ceramics were processed under different conditions of temperature and annealing. Crystal orientations in the bulk ceramics were examined and the results were plotted in microtexture pole- and inverse pole-figures. Local texture and misorientation between adjacent grains in certain selected regions of the ceramics were also examined. To compare the results of the PST with another lead-based ferroelectric material, an unpoled and a poled PZT ceramics were studied for their texture. The electrical and electromechanical ...Effective Elastic Properties of Textured Cubic Polycrystals
Updated: 2009-11-03 15:28:46A general scheme for the solution of problem of averaging elastic properties of textured polycrystals is suggested which is based on the algebraic methods of description of elastic properties.

Updated: 2009-11-03 15:28:46Using finite elements over Rodrigues space, methods are developed for the formation and inversion of pole figures. The methods take advantage of the properties of Rodrigues space, particularly the fact that geodesics corresponding to pole figure projection paths are straight lines. Both discrete and continuous pole figure data may be inverted to obtain orientation distribution functions (ODFs) in Rodrigues space, and we include sample applications for both types of data.

Updated: 2009-11-03 15:28:46The strain and phase distribution in a dissimilar friction stir weld of AA6082-T6 to AA2024-T3 is investigated non-destructively. The measurements are performed using a novel depth resolved strain and phase mapping technique. The technique is based on the use of a focussed high energy synchrotron beam, a novel spiral slit system, and an area detector system. Through thickness measurements of the residual strain along the weld centre show strong variations with changes of sign. The strain scans across the weld exhibit a strong asymmetry in particular for the longitudinal strain component. A depth resolved strain mapping across the weld shows for the dominant longitudinal strain component variations in depth, especially on the AA6082 side of the weld. Results from the strain measurements are...Tensile Deformation Induced Texture Transformation in Austenitic Stainless Steel
Updated: 2009-11-03 15:28:46Texture patterns of the starting ώ and transformed α structural phases were obtained from AISI 304 stainless steel sheets subjected to varying levels of tensile deformation using high energy X-ray diffraction in combination with the texture enhanced Rietveld method. The use of this method allows the simultaneous determination of the orientation distribution functions (ODF) of both phases, even for small α-martensite fractions of the order of 5%. The texture patterns are analyzed in terms of the crystallographic orientation relation between the starting and transformed phases and the preferential formation of certain variants of this relation.

Updated: 2009-11-03 15:28:46Triaxial strain scanning has been performed on a 7mm thick 7150-aluminium alloy Variable Polarity Plasma Arc (VPPA) weld using synchrotron X-rays. It has been demonstrated that the use of specific advantageous (hkl) peaks that occur in this highly textured aerospace alloy plate permits fast deep measurements in reflection as well as in transmission. The sin2ψ method was also utilised to monitor the variation in deviatoric stress component (σ11−σ33) across the weld in both the test-piece and a comb like reference specimen used to map the changes in stress-free lattice spacings over the weld. The results suggest that microstresses have little effect on macrostress determination, particularly in the Heat Affected Zones (HAZ). Though small in magnitude, the ...Use of Synchrotron Diffraction Data for Describing Crystal Structure and Crystallographic Phase Analysis of R-Phase NiTi Shape Memory Alloy
Updated: 2009-11-03 15:28:46The objective of the present article is to use the third generation synchrotron X-ray source at the European Synchrotron Research Facility (ESRF) in Grenoble, which make available X-ray beams of higher energy and much higher intensity than laboratory X-ray sources, for describing crystal structure of the R-phase in 50.75 at.% Ti–47.75 at.% Ni–1.50 at.% Fe ternary alloy. The synchrotron diffraction data of R-phase were analyzed using the Rietveld refinement with GSH description. The results showed that no significant improvement in fit is found when the inversion center is removed from the P3¯ model, suggesting that the space group is indeed P3¯ and not P3.

Updated: 2009-11-03 15:28:46The present work is devoted to the study of the grain number influence on the quantitative texture analysis and on the values of averaged elastic properties. Number of grains does not influence mathematical definition of orientation distribution function (ODF) (Bunge, H.J. (1982). Texture Analysis in Material Science. Butterworths, London; Matthies, S., Vinel, G.W. and Helming, K. (1987). Standard Distributions in Texture Analysis. Akademie-Verlag, Berlin.); nevertheless, intuitively clear that, averaging procedure implies a ‘‘large’’ number of grains to make sense. In the present work we applied the already suggested procedure (Lychagina, T.A. and Nikolayev, D.I. (2003). Phys. Stat. Sol. (a), 195(N2), 322–334.) for the case of hexagonal symmetry to evaluate the influence of the ...High-Energy X-Rays: A tool for Advanced Bulk Investigations in Materials Science and Physics

Updated: 2009-11-03 15:28:46In order to describe texture and microstructure of a polycrystalline material completely, crystal orientation g={ϕ1Φϕ2} must be known in all points x={x1 x2 x3} of the material. This can be achieved by locationresolved diffraction of high-energy, i.e. short-wave, X-rays from synchrotron sources. Highest resolution in the orientation- as well as the location-coordinates can be achieved by three variants of a detector “sweeping” technique in which an area detector is continuously moved during exposure. This technique results in two-dimensionally continuous images which are sections and projections of the six-dimensional “orientation– location” space. Further evaluation of these images depends on whether individual grains are re...Intensity Correction in Texture Measurement of Polycrystalline Thin Films by X-Ray Diffraction
Updated: 2009-11-03 15:28:46The tilting of a specimen may not only result in defocusing effect, but also in a change of irradiated volume during texture measurement for thin films and coatings by using X-ray diffraction. The influence on diffraction intensity has to be considered in order to obtain an accurate result of texture analysis. The effect of irradiated volume can be formulated as a function of the thickness and the linear absorption of a studied film material, the tilt angle of the specimen and the Bragg angle of diffraction, and then eliminated. In view of that the preparation of a randomly oriented specimen would be difficult, a simple and convenient method is hereby proposed to correct the defocusing effect from known data of existing bulk powder specimens with random orientation by interpolation (or ext...Effect of Gravity on the Kinetics of Consolidation of Powder Bodies
Updated: 2009-11-03 15:28:46Physical mathematical model of sintering powders is suggested with respect to the influence of gravitation on sintering kinetics.
