摘要
研究了65Cr5Mo3W2VSiTi钢马氏体-贝氏体复相组织组成物相对量和回火温度对冲击疲劳性能的影响，提出了提高抗冲击疲劳强度的强韧化热处理工艺。
Investigation was carried out on impact fatigue life of 65Cr5Mo3W2VSiTi steel(LM2) with various relative amount of bainite and martensite tempered at various temperatures. A strengthening-toughening heat treatment process would be proposed for cold working dies of LM2 steel against impact fatigue load.
