| 摘 要： | 通过对W18Cr4V合金工具钢在清水、锭子油和高压气体等淬火介质中淬火对比实验,研究W18Cr4V合金工具钢在不同介质淬火工艺处理后的硬度和微观结构.研究结果表明,水淬火时试件表面与中心的温差较大,锭子油次之,高压气体较小;试件高压气体淬火时,温度剃度小,内部冷却比较均匀,可以预计,相应的热应力和热变形也比较小;应用较小压力的氮气能够实现淬透性比较好的W18Cv4V工具合金钢的高压氮气淬火处理.

| Abstract: | The hardness and micro - structures of W18Cr4V alloy steel in various quenching media after quenching were investigated by means of contrastive experiments. The obtained results showed that (1) the temperature differences between the axis and the surface of the cylinder were largest during water quenching, intermediate during oil quenching, and smaller during gas quenching; ( 2 ) the temperature gradient of work -pieces is smaller during gas quenching and it can be predicted that corresponding thermal strains and thermal stresses are also smaller than during water and oil quenching; (3 ) the gas quenching technology during small pressure can be realized for good quench -ability W18Cr4V alloy steel. |

| Keywords: | W18Cr4V alloy steel gas quenching temperature phase transformation. |
