摘要
采用中间合金法制备了纳米SiC强化ZGMn13Cr2样品。研究了添加纳米SiC对ZGMn13Cr2样品显微组织和力学性能的影响。研究结果表明:经改性纳米SiC粉末强化处理后的超高锰钢的组织有显著改善,力学性能明显提高,当SiC含量为0.3‰时,硬度和冲击吸收功分别提高了11%和12%。通过扫描电镜和能谱分析可以得出:SiC分解为Si和C存在于奥氏体基体中,并促进碳化物弥散分布于基体上,起到强化基体的作用。
The ZGMn13Cr2 samples reinforced by nano SiC were prepared under industrial conditions. The mechanical properties and microstructure of ZGMn13Cr2 samples with SiC nano-powders were investigated. The results show that the organization of high manganese steel strengthen by SiC intermediate alloys is refined obviously and the mechanical properties are improved significantly. With the SiC content of 0. 3‰,the hardness and impact absorbed energy are increased by 11% and 12% respectively. The results obtained through the SEM and EDS analysis show that Si and C decomposed by SiC exist in austenitic promoting the carbides to distribute in the martix,and the austenitic martix is strengthen.
