摘要
强烈塑性变形可以用于制备超细晶金属材料,超细晶金属材料一个典型的特性是具有高应变率和/或低温超塑性。介绍利用强烈塑性变形研制超塑铝、镁合金的研究近况,并对强烈塑性变形超塑材料的研究进行展望。
Severe plastic deformation is an effective tool to develop ultrafine-grained metals, and one of the typical properties of ultrafine-grained metals is enhanced superplasticity. In this paper, typical examples of this superplastic behavior are presented for several aluminum alloys and for magnesium alloys. It is suggested that severe plastic deformation is an effective tool to develop enhanced superplasticity of aluminum-based alloys.
