摘要
测试了M2高速钢在不同温度时的淬火和回火后的硬度、红硬性和抗弯强度,分析了影响红硬性和韧性的各种因素,发现淬火温度对红硬性影响明显,回火温度对红硬性影响不明显;淬火温度和回火温度对韧性均有明显的影响;就改善M2高速钢韧性而言,提高回火温度比降低淬火温度更有效。
The hardness, red hardness and bending strength after quenching and tempering were determined, and the factors
of influence on red hardness and toughness were analysed. It was found that the quenching temperature strongly influenced
the red hardness than tempering temperature; The quenching and tempering temperature both evidenily influenced on strength
and toughness. For improve the toughness, increasing the tempering temperatur is more effective than reducing the quenching
temperature.
