| 摘 要： | 研究了铜对Fe-22.5/30 Mn-3Al-3Si TWIP钢的显微组织和力学性能的影响规律。结果表明,随着铜含量的增加,TWIP钢中奥氏体平均晶粒尺寸减小。铜含量超过0.5wt%后,TWIP钢的显微硬度明显提高。TEM观察显示TWIP钢未形变时组织中存在许多层错群和规则排列的位错列,形变后出现大量密集排列的形变孪晶和被形变孪晶分割的位错。

| Abstract: | Effects of Cu on the microstructure and properties of a twinning induced plasticity(TWIP) alloys were investigated.The results show that the grain size is reduced with increasing the amount of Cu.The hardness is significantly enhanced when the Cu exceeded a certain amount.Dislocations and stacking fault arrays were observed in the pre-deformed TWIP alloys,and lots of deformation twins were found in the deformed alloys. |

| Keywords: | TWIP alloy microstructure mechanical property deformation twin |
