アルミニウム⟨111⟩対称傾角粒界の粒界すべり

抄録

Grain boundary sliding parallel or normal to the ⟨111⟩ tilt axis was investigated for symmetric tilt boundaries in aluminum.
The rate of grain boundary sliding parallel to ⟨111⟩ was smaller than that normal to ⟨111⟩. This difference in the rate of grain boundary sliding coincided with the model proposed by McLean. The orientation dependence of the grain boundary sliding rate, however, could not be explained by his model.
Unusual decrease in the sliding rate was found on the Σ7 coincidence boundary.
