Materials and Methods The titanium samples, both CP Ti and Ti alloy, were machined from a titanium rod without lubricant and with a HSS tool, then polished on a Leco Auto polisher to a 1 micron finish, before the final polish in a vibratory polisher with an alpha alumina to 0.5 micron finish.
During testing, the materials were immersed in diluted bovine serum (50% serum, 50% deionized water).

Abstract: The evolution of microstructure and texture in Hexagonal Close Pack commercially pure titanium has been studied in torsion in a strain rate regime of 0.001 to 1 s-1.
Introduction Torsion tests have been employed to study the deformation behaviour at large strains for variety of materials [1-2].
All the curves showed three different stages of strain hardening namely stage A, B and C that are commonly observed for hexagonal materials that deform by twinning [6].

Abstract.
Composite material coefficient of thermal expansion anisotropy and layer direction asymmetry caused by the coupling effect, make the composite materials in temperature change structure internal produce thermal stress.
In the finite element software, can through the laminated unit or multilayer unit of composite materials for modeling, and structural analysis and thermal analysis.
Composite material of each layer of material properties and the direction of the layer may be different, so the composite material modeling than the average isotropic material is very difficult.
