摘要
介绍了各种合金结构钢(铁素体钢、铁素体-珠光体钢和淬火回火钢)的形变位错结构及循环形变位错结构的研究情况,阐述了沉淀硬化合金强化过程的位错缠结机制、静载和动载竞争机制以及循环微裂纹的萌生机制。
The deformation dislocation structures and cyclic deformation dislocation structures of several alloy structural steels （ferritic steel, ferrite-pearlite steel and quench-tempered steel） were studied. The dislocation tangle mechanism of strengthening process for the precipitation-hardening steel, competitive mechanisms of static and cyclic loading, and nucleation mechanism of cyclic microcrack were expounded.
