AbstractThe anisotropy in room temperature plastic deformation has been investigated in single α(HCP)/β(BCC) colonies of a commercial α/β titanium alloy (Ti-6Al-2Sn-4Zr-2Mo-0.1Si) oriented for activation of individual basal slip systems. Detailed transmission electron microscopy (TEM) studies of the slip transmission mechanisms through the α/β interfaces have been performed to elucidate the role of these interfaces in determining yield and strain hardening behavior. Significant anisotropy in the yield strengths and hardening rates for the 3 unique basal slip systems is measured, and is attributed to the different slip transmission mechanisms active due to the near-Burgers orientation relationship existing between α- and β-phases. These results are should be transferable to other alloy systems exhibiting this orientation relationship.

The effect of annealing treatments on the evolution of the strain rate sensitivity with strain of AZ61 magnesium alloy processed by severe rolling was investigated and related to previous results on normal plastic anisotropy (r-value). The various annealing treatments produce two effects on the microstructure: grain coarsening and slight weakening of the texture. In addition, these treatments produce a noticeable decrease in strain rate sensitivity and an increase of work hardening rate that is related to the decrease of the anisotropy. It is concluded that these effects are related to an enhanced contribution of basal slip as a consequence of the microstructural changes induced by the annealing treatments.
