Zn対応粒界における粒界移動-粒界すべりとそのDSC転位モデル

抄録

A coupling of grain boundary migration and sliding was observed on the {1\bar211} coincidence boundary in a Zn bicrystal, viz. 0.52 rad ⟨10\bar10⟩ symmetric tilt boundary, under applied shear stress at high temperature. The ratio of the amount of grain boundary migration to that of sliding, which was measured to be ∼2, and the migration direction were in accordance with the DSC dislocation model’s prediction.
