摘　　要：为了改善高锰钢的组织性能,提高其铸件的质量。对原始高锰钢进行了钨元素的合金化处理,采用金相组织分析硬度测试、抗拉分析等手段研究了钨合金化处理后高锰钢的组织与性能。结果表明:随着钨含量的增加,高锰钢的晶粒明显细化,夹杂物的尺寸和分布也得到了改善。机械性能方面,合金高锰钢的硬度提高了17.5%~47.4%,最高能达到25.2 HRC。抗拉强度随着钨元素的加入也得到改善,提高了7.9%~17.7%,最高能达到491 MPa。钨合金化处理能够改善高锰钢的硬度和抗拉强度。In order to improve the microstructure and properties of high manganese steel,improve the quality of its castings,the microstructure and properties of raw high manganese steel after tungsten alloying were studied by means of metallographic structure analysis,hardness test and tensile analysis.The results show that with the increase of tungsten content,the grain size of high manganese steel is obviously refined,and the size and distribution of inclusions are improved.In terms of mechanical properties,the hardness of alloy high manganese steel is increased by 17.5%~47.4%,and the highest hardness can reach 25.2 HRC.The tensile strength is also improved with the addition of tungsten element,which is increased by 7.9%~17.7%,and the maximum tensile strength reaches 491 MPa.Tungsten alloying can improve the hardness and tensile strength of high manganese steel.
