用多晶塑性模型模拟了铸造镁锌合金的拉伸屈服和压缩屈服，得到了不同晶粒度和成分的镁锌合金。结果被用来确定晶粒度和成分的依赖关系的临界分解剪应力(CRSS)的基础上滑移和拉伸孪晶。(C)2010年Acta Materialia Inc.由爱思唯尔有限公司出版。版权所有。
The tensile and compressive yielding of cast Mg-Zn alloys, with varying grain sizes and compositions ranging from 0 to 2.3 at.% Zn, are simulated using a polycrystal plasticity model. The results are used to determine the grain size and composition dependences of the critical resolved shear stresses (CRSS) of basal slip and tensile twinning. (C) 2010 Acta Materialia Inc.
