【Abstract】 The relationship of residual austenitic content and distribution with the martensitic lath size for 30SiMnCrMoV steel was obtained under different prestrain heat treatment. On the basis of the D Nucleation Theory developed in recent years and the Energy Dilution Principle for invariant plane strain, the relationships were analyzed. The results show that the relationship of residual austenitic content and distribution with the martensitic lath size for 30SiMnCrMoV steel under prestrain heat treatment is consistent with the D Nucleation Theory and Energy Dilution Principle for invariant plane strain.更多还原
