板材连续剪切变形工艺研究现状及展望
|
摘要
板材连续剪切变形(CCSS)是在等径角挤压基础之上研发的一种可连续剪切变形制备纳米块体材料的剧烈塑性变形工艺。概述了CCSS制备技术的工作原理及其优缺点。综述了CCSS的国内外研究现状,分析了CCSS目前存在的问题,并对它的应用前景作了展望。
The continuous confined strip shearing(CCSS) is a severe plastic deformation(SPD) process of preparation of nanocrystalline bulk materials by continuous shear deformation, which is developed on the basis of equal channel angular pressing. The principle, advantages and disadvantages of CCSS process were summarized. The research status of CCSS in China and other countries were also summarized. The current problems were analyzed. And its application prospect was forecasted.
