| 摘 要： | 采用氩气吹人法制备纳米TiN粉末强化ZGMn13样品,研究了纳米TiN对ZGMn13显微组织和力学性能的影响.结果表明,经纳米TiN粉末强化处理后的高锰钢的组织明显细化,力学性能明显提高.透射形貌分析和衍射花样标定得出:纳米级TiN以0.5916％的错配度存在于基体中,可作为异质形核剂细化高锰钢晶粒,强化基体,并分析了纳米TiN在高锰钢中的作用机理. |

| Abstract: | The ZGMn13 samples reinforced by TiN nano-powders were prepared by Argon method in industrial conditions.The mechanical properties and microstructure of TiN reinforced ZGMn13 samples were investigated.The results show that the microstructure of TiN reinforced ZGMn13 refines obviously and the mechanical properties improves significantly.Transmission topography analysis and electron diffraction pattern show that Nano-TiN exists in the matrix with the mismatch of 0.591 6% between austenite and TiN,and it can refine the grains of high-manganese steel as heterogeneous nucleation agents,and strengthens the matrix.The mechanism of nano-TiN in high-manganese steel was analysed. |
| Keywords: | TiN nano-powders high-manganese steel mechanical properties microstructure |
