説明

Active twinning systems during compression deformation at temperatures from 25°C to 700°C were investigated using SEM/EBSD techniques in order to clarify the effects of oxygen and aluminum addition on twinning deformation in titanium. Four twinning systems have been confirmed in commercially pure titanium, Ti-0.2mass%O and Ti-2mass%Al under compression at 10% strain. The addition of oxygen suppresses the activity of all the twin systems at 25°C, but only slightly above 200°C. On the other hand, the addition of aluminum suppressed the activity of only the {112̅2} twin. It is supposed that the suppressive effect of the oxygen addition is mediated by thermal activation processes such as diffusion and lattice vibration, while that of the aluminum addition is brought about by the suppression of <c^+a> slip.
