摘要
对等径角挤压工艺的基本原理及其工艺参数在挤压过程中对镁合金显微组织、力学性能的影响,等径角挤压过程中镁合金的晶粒细化机理、变形机理及其微观结构、力学性能等的演变规律作了综述,并对等径角挤压镁合金超塑性研究现状和镁合金等径角挤压发展趋势作了介绍。
The basic principle of equal channel angular extrusion(ECAE) and the influence of technological parameters for ECAE process on extruded magnesium alloys are reviewed. The grain refining mechanism, deformation mechanism, the change of microstructure and mechanical properties of magnesium alloys during ECAE processing are discussed. Superplasticity of magnesium alloys processed by ECAE and the trend of development of magnesium alloys are introduced.
