变形机理图的研究进展及发展趋势

摘要

变形机理图又称为塑性变形的相图,它对材料变形过程的预报对于材料成形科学基础研究具有重要的意义.文中分别对Ashby、Langdon-Mohamed、Ruano-Wadsworth-Sherby、含位错数量的R-W-S变形机理图的构建方法、使用条件及特点进行了介绍.为变形机理图在实际生产中的应用提供了理论基础.%Deformation mechanism map, I.e. Plastic deformation map, is effective to predict the material deformation during processing, which is very important for basic research on material processing. The constructing method, applying conditions and characteristics for the four deformation mechanism maps are introduced, for example, Ashby, Langdon-Mohamed, Ruano-Wadsworth-Sherby and dislocation R-W-S, respectively. The deformation mechanism map is the basic theory for application on production.
