热挤压Mg-Zn-Al合金的屈服应力具有明显的晶粒尺寸依赖性。然而，相同的摩擦搅拌处理的镁锌铝合金样品表现出弱得多的晶粒尺寸依赖性。摩擦搅拌处理的样品的约0.3的高Schmid因子是造成Hall-Petch关系中的低参数的原因。(c)2006 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
The Mg-Zn-Al alloy processed by hot extrusion typically exhibits strong grain size dependence of yield stress. However, the same friction stir processed Mg Zn-Al alloy samples exhibited much weaker grain size dependence. The high Schmid factor of around 0.3 of the friction stir processed samples is responsible for the low parameters in the Hall-Petch relationship. (c) 2006 Acta Materialia Inc.
