| 摘 要： | 用定量金相法研究了Gleeble1500D自动热模拟机1200℃热处理和1050～950℃40%～60%热变形对3mmM2(W6Mo5Cr4V2)高速钢铸带中碳化物直径,体积分数的影响。研究结果表明,高温热处理和热变形可细化M2钢铸带中的碳化物尺寸,改善碳化物分布;1200℃40min热处理+50%热变形可得到较细的碳化物(0.96μm)和均匀的分布。

| Abstract: | The effect of 1200 ℃ heat treatment and 40%～60% hot deformation at 1050~950℃ on diameters and volume fraction of carbide in 3 mm cast-strip of high speed steel M2(W6Mo5Cr4V2)using Gleeble 1500D auto thermo- simulation machine have been studied by quantitative metallographic examination. The studied results showed that the car bide size in steel M2 was fined and distribution of carbide was improved in cast-strip by high temperature heat treatment and hot deformation,and 1200 ℃ 40 min heat treatment + 50% hot deformation was available to get fine carbide(0.96 μm) and homogeneous distribution. |
