摘　　要：探讨一种改善耐磨高锰钢碳化物形态的热处理工艺。结果表明,水韧处理结合高压热处理和常压热处理可以有效地改善耐磨高锰钢组织中析出碳化物形态及分布,经水韧处理后再经5 GPa、650℃保温30 min的高压热处理和750~800℃保温60 min的热处理,耐磨高锰钢可获得弥散分布的颗粒状和短条状碳化物。A heat treatment process for improving carbide morphology of wear resistant high manganese steel was discussed.The results show that the morphology and distribution of precipitated carbides in this wear-resistant high manganese steel can be effectively improved by water toughening treatment combined with high pressure heat treatment and atmospheric pressure heat treatment.After water toughening treatment,the wear-resistant high manganese steel can obtain dispersed granular and short strip carbides after 5 GPa,high pressure heat treatment at 650℃for 30 min and heat treatment at 750-800℃for 60 min.
