本文综述了微细晶粒超塑变形的力学特征,并从Zn-Al合金状态图,Zn-22%Al合金TTT曲线等阐明了Zn-Al共析合金的超塑性特点和应用,并对组织超细化和性能强化的方法进行了探讨。
In this paper, the mechanical characteristics of fine grain superplastic deformation are reviewed. The superplasticity and application of Zn-Al eutectoid alloy are illustrated from the state diagram of Zn-Al alloy and the TTT curve of Zn-22% Al alloy. Refinement and performance enhancement methods were discussed.
