摘要
本文从强韧化机制方面，研究了用于铝合金型材挤压模具的３Ｃｒ２Ｗ８Ｖ钢在不同热处理工艺条件下的金相组织，显微结构与断口，常温与高温下的力学性能．结果表明，采用１２５０℃以上超高温淬火加４００－５００℃中温回火的强韧化处理工艺，可使该钢同时获得具有良好力学性能和较好韧性、热强性、热稳定性、热疲劳性、耐磨性等相结合的综合性能．
Based on the high toughness mechanism, the relationships between heat treatment processes and the microstructure, fracture, characteristics, and mechanical properties at room and high temperatures of extrusion die steel 3Cr2W8V were studied. The results showed that by employing the process of super-high temperature quenching (over 1250℃) and medium temperature tempering (400-500℃), the extruion die steel 3Cr2W8V can obtained good comprehensive properties, including high toughness, thermo-strength, thermo-stability, thermal fatigue and abrasion resistance etc.
