国内国外近几十年来介绍合金塑性变形的基础理论书籍很多。但是关于工程结构及机械制造中大量应用的结构钢,尤其是淬火回火钢的形变位错结构的研究却是很少见的。只有在加载过程的进行中深入研究位错结构的演变规律才能正确把握材料的力学性能的本质。此书作者能够在变形度的增 At home and abroad in recent decades to introduce plastic deformation of the basic theory of many books. However, the research on the structural deformation dislocation structure of the structural steel, especially the quenched and tempered steel, which is widely used in the engineering structure and machinery manufacturing is very rare. Only in the loading process in-depth study of the evolution of dislocation structure in order to correctly grasp the nature of the mechanical properties of materials. The author of this book can increase the degree of deformation
