摘　　要：研究了在加热过程中，高温加热时间对Ｗ９、Ｍ２、Ｍ２Ａｌ、Ｄ６０６高速钢脱碳的影响，实验结果表明；当一定温度下，Ｗ９、Ｍ２、Ｍ２Ａｌ、Ｄ６０６高速钢的脱碳层深度与保温时间的平方根成正比，Ｗ９、Ｍ２、Ｍ２Ａｌ、Ｄ６０６的脱碳敏感温度均为１１００℃。The influence of high-temperature heating time to decarbonization of high-speed-steel of W9, M2. M2AJ, D606 in heating process is researched. It is showed from the experiment that under some temperature the depth of decarbonized layer of above high-speed-steels is proportional to the square root of time of keeping temperature, and their sensitive decabonization temperature are all 1100℃

关 键 词：高速钢 脱碳 加热时间 加热温度 热加工
