摘要
等径弯角挤压是制备块状细晶材料的一种大塑性变形工艺,目前得到国内外高度重视。本文简要介绍了等径弯角挤压工艺的基本原理和变形特点,从理论上对其变形方式和机理进行了分析,并详细介绍了该工艺的应用领域。
The Equal - Channel Angular Extrusion Process (ECAEP) , as one of the severe plastic deformation processes of making fine - grained bulk materials, is subjected to intensive attention, both at home and abroad. The basic principles and deformation features of the ECAEP are illustrated briefly, its deformation mechanism analyzed, and the main application areas of the process presented in detail in this paper.
