| 摘 要： | 研究了钢的微观结构，残余奥氏体的稳定性及力学性能随回火温度的变化，结果表明；钢的基体为细晶马氏体，且大部分具有位错亚结构；马氏体板条界上存在着较稳定的残余奥氏体薄膜；马氏体内均匀分布着大量固溶时未溶，５－５０ｎｍ大小的Ｖ４Ｃ３；２００－３００℃回火析出大量细小的ε－碳化物。这种微观结构对于获得高强韧性是理想。Ｓｉ使ε－碳化物溶解和渗碳体的形成温度提高到３００℃以上，故钢在２００－３００℃回火有良好

| Abstract: | A new high-strength high-toughness low alloy cold-working die steel 6CrNiMnSiMoV (GD Steel) has been developed. The amount of alloy elements in the steel is less than 5%, but the strength and toughness of the steel are superior to that of CrWMn and Cr12Mo |

| Keywords: | strengthening-toughening cold-working die steel microstructure |
