在不同淬火温度、冷处理方式和回火温度下对 W2Mo9Cr4VCo8高速钢的硬度及组织进行试验研究，结果表明：在1150～1220℃淬火，随着淬火温度的提高，淬火硬度有逐渐下降的趋势；在不同的冷处理工艺和520，535，550℃温度下回火3次，试样的硬度及回火组织差别不大；不同淬、回火温度下，回火3次后试样的残余奥氏体含量均为零。基于试验分析优化了 W2Mo9Cr4VCo8的热处理工艺。

The hardness and structure of high speed steel W2Mo9Cr4VCo8 are experimentally studied under different quenching temperature,cold treatment mode and tempering temperature.The results show that the quenching hardness gradually decreases with the increase of quenching temperature when quenching temperature is 1 1 50 ~1 220 ℃.Af-ter different cold treatment and tempering at 520,535 and 550 ℃ temperature,there are not significant differences for hardness and tempering microstructure.The content of residual austenite after tempering three times is zero under dif-ferent quenching and tempering temperature.The heat treatment technology for W2Mo9Cr4VCo8 is optimized based on experimental analysis.
