简述了高速钢的应用及发展情况,在此基础上讨论合金元素Al对高速钢红硬性的影响。
2.
The hardness, red hardness and bending strength after quenching and tempering were determined, and the factorsof influence on red hardness and toughness were analysed.
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。
