Hot Rolled

Uniaxial compression tests on hot-rolled AZ31 Mg alloy were carried out at 200°C. In order to investigate the evolution of texture during plastic deformation, cylindrical specimens were compressed to the rolling and normal directions. Experimental investigation reveals that work hardening and texture evolution are strongly dependent on the loading direction. The occurrence of deformation twinning was revealed by the observation of microtexture using electron backscatter diffraction (EBSD). A visco-plastic self-consistent (VPSC) polycrystal model was used to simulate the texture evolution during the uniaxial compression. The texture evolution induced by crystallographic slip and deformation twinning can be explained by the relative activity of each deformation modes.

Strain Hardening Rate

Texture and cyclic tensile behavior of Ti-26Nb-0.5Si (denoted as atomic percent) alloys in which the microstructures were varied by quenching, cold rolling and recrystallization heat treatment were investigated in order to understand the relationship between pseudoelastic behavior and texture formation. Three phase mixtures consisting of bcc-structured β phase, orthorhombic structured α" phase and hcp-structured intermediate ω phase were characterized to display the constituent phases. The volume fraction of constituent phases was found to be insensitive to the given materials processing. Two-stage yielding, one at low stress with low strain hardening rate and the other one at high stress with high strain hardening rate, appeared to exhibit a characteristic flow behavior in the present alloys. It is revealed that stress-induced martensite transformation resulting in two-stage yielding was closely associated with pseudoelasticity. On the basis of texture analyses, we have suggested that pseudoelasticity of the present alloys is hindered by the development of {001}<110> rotated cube component.
