摘要
综述了等径角挤压制备超细晶材料领域的最新研究进展,包括等径角挤压的工艺原理,显微组织演化规律,等径角挤压材料微观组织特征和力学性能等。
Ultra-fine grained materials produced by equal channel angular pressing(ECAP) have been inten- sively investigated in the past several years.Much improvement has been made in foundemental understanding and practical application of these materials.This article reviews the present state of this field,including the principle of the technigue,deformation behaviour and microstructural evolution during ECAP,structural characterization and mechani cal properties of ECAPed materials.
