摘　　要：采用马氏体一贝氏体复相热处理研究了３Ｃｒ２Ｗ８Ｖ钢强韧化工艺，并作了理论分析．将试验结果用于Ａ１合金压铸模，显著提高了耐磨性，抗热疲劳性和使用寿命．By (M+B) dual-phase heating treatment,strengthening and toughening technique of 3Cr 2W 8V steel is studied and analysed.The experimental result could be used for the aluminium-alloy die of pres=casting machine;and their wear resistance,antiheating fatigue resistance and service lives could be greatly improved.
