| 摘 要： | 研究了中碳-高Mn系TWIP钢在固溶处理后的组织和力学性能。采用OM、XRD、TEM和EBSD分析了TWIP钢形变前后的微观组织演变规律和高强塑性的产生机理。结果表明，形变孪晶密度随着变形程度的增加而增大，形变孪晶渐进产生，细化起到细晶强化和延缓断裂的作用，使TWIP钢具有优异的综合力学性能和成形性能。

| Abstract: | The microstructures and mechanical properties of a TWIP steel with medium carbon-high manganese after solid solution treatment are studied.The regularities of microstructures evolution and the forming mechanism of high strength and plasticity before and after deformation of the TWIP steel are analyzed by OM,XRD,TEM and EDSD.The results show that the density of deformation twins increases with the deformation degree increasing while the gradual forming and fining of deformation twins play a role in the fine ... |
