摘要
本文综述了等径角挤压技术(Equal Channel Angular Pressing,ECAP)、高压扭转变形技术(High Pressure Torsion,HPT)、多向锻造技术(Multiple Forging,MPF)和高应变速率轧制技术(High Strain Rate Rolling,HSRR)4种典型强塑性变形技术在镁合金中的应用现状,分析其应用局限性,并指出了当前强塑性变形技术的发展方向。
The application and development of 4 typical techniques of severe plastic deformation (equal channel angular pressing,high pressure torsion,multiple forging and high strain rate rolling)in magnesium alloys were critically reviewed,and their application limits were analyzed. Furthermore,suggestions were made for the future development of severe plastic deformation.
