摘要：
The relationship between grain orientation and twin variant selection during compression of the alloy Mg-3%Al-1%Zn has been investigated, and methods for obtaining such information described. Some important aspects of the observed twinning cannot be accounted for by a simple Schmid factor type parameter. In particular, in grains containing two twin variants, one of the twin variants has a substantially lower Schmid factor than that predicted from such a simple analysis. (c) 2007 Acta Materialia Inc.
