摘要
采用三点弯曲、单边Ｖ型缺口试样，沿缺口渗碳，测试渗碳淬硬层断裂韧性的试验方法，研究了碳、氮含量和冷处理及回火温度对Ｍ５０ＮｉＬ钢渗层断裂韧性的影响。结果表明，渗碳层中附加渗入微量氮对二次硬化和断裂韧性的提高都有利。
A new test method of fracture toughness for carburized and case hardened steel has been developed The effect of C N content and tempering temperature on fracture toughness of carbon nitrogen case hardened M50NiL steel were studied The secondary hardening effect and crack resistance of M50NiL steel are apparently increased by a slight nitrogen addition
