| 摘 要： | 采用三种工艺对成分为25Mn-3Si-3Al的TWIP钢进行了试制，并对轧后钢板的组织性能进行了对比分析。结果表明，轧制后退火处理钢板的室温组织为奥氏体基体中存在大量的退火孪晶，在拉伸变形中形成的形变孪晶使产品获得了高强度、高塑性。

| Abstract: | The rolling experiments of 25Mn-3Si-3Al TWIP steel were carried out at the conditions of different processes, and its microstructures and mechanical properties were analyzed comparatively. The results show that, most annealing twin microstruc- ture distribute in austenite matrix of annealed sample, and the deformation twin formed during tensile strain make the sample attain high strength and high plasticity. |
