摘要
Ａｌ－Ｌｉ二元单晶体的流变应力和应变速率，温度以及时效状态的关系可以符合动态应变时效的理论。负的应变速率敏感性是Ａｌ－Ｌｉ合金中锯齿流变产生的必要条件。
The flow stress of Al-Li single crystals was investigated with the changes of strain rates, temperatures and aging conditions the results show that the variations of the flow stress can be rationalized with the dynamic strain aging theory. The negative strain rate sensitivity is a necessary condition for the occurrence of the serrated flow in Al-Li single crystals.
