| 摘 要： | 本文对Fe-26Mn-6A1-1C钢的力学性能及微观组织进行了分析。研究结果表明，该成分的高锰钢层错能为60mJ／m^2。，固溶态的屈服强度为450MPa，抗拉强度为780MPa，伸长率为58％，并呈连续屈服。在变形过程中，不发生相变。当变形程度低于30％时，实验钢的主要变形机制是位错滑移，并形成了亚结构，不发生显著的TWIP（twinning induced plasticity）效应。

| Abstract: | In this paper, the mechanical properties and microstructures of a Fe-26Mn-6A1-1C steel were investigated. The results showed that the steel with a stacking fault energy of 60mJ/^m2 in a solution treated state possessed a yield strength of 450MPa, tensile strength of 780MPa and elongation of 58%. The steel exhibited continuous yielding. No phase transformation occurred during the deformation process. The dominate deformation mechanism of the steel was dislocation slip and substructures have been formed when the strain was lower than 30% and no obvious twinning was found. |
