摘要(Abstract)：

采用扫描电镜、透射电镜等研究了低合金耐磨钢经低温回火、循环热处理、一步配分热处理后的显微组织,采用磨粒磨损试验机测试其磨损质量。结果表明:试验钢经低温回火后的组织为板条马氏体加少量析出相;循环热处理的试验钢的马氏体板条消失,在原奥氏体晶界上和基体处均有碳化物析出相;淬火配分热处理的试验钢中的马氏体板条比较明显,并有少量的残留奥氏体。能谱成分分析可知,不同热处理工艺后试验钢中的微米尺寸的析出相主要是(Ti, Nb)C,球形与椭球形纳米尺寸析出相是(Ti, Nb, V,Mo)C。淬火加200℃低温回火处理的试验钢的硬度为46.5 HRC,循环热处理的试验钢的硬度最低,为31.48 HRC,淬火加一步配分热处理的试验钢的硬度为44.84 HRC。磨粒磨损实验结果表明,淬火加200℃低温回火处理后的试验钢的耐磨损性最佳,淬火加配分处理的试验钢的磨粒磨损性能与淬火加低温回火的试验钢相差不大,循环热处理的试验钢的磨粒磨损性能较差。
