| 摘 要： | 研究了X20CoCrWMo10-9热作模具钢在1 000～1 180℃淬火温度下的组织和性能,并确定材料的最佳淬火温度为1 120℃;经不同工艺深冷处理后对钢进行显微组织观察和力学性能测试。结果表明,深冷处理可以不同程度提高钢的硬度和耐磨性。对比不同回火温度与时间下的性能,制定该钢适宜的深冷处理工艺为:1 120℃淬火+深冷处理8 h+650℃×1 h回火。

| Abstract: | The effects of various heat treatments on hot die steel X20CoCrWMo10-9 were investigated.By analyzing phase structure,microstructure and properties of the steel,optimal quenching temperature of 1 120 ℃ was identified.It was also found that deep cryogenic treatment would improve the hardness and abrasion performance of the steel.After comparison between performances at different tempering temperature and for different length of time,it was concluded the desirable heat treatment process should include the following steps: quenching at 1 120 ℃ plus 8 h deep cryogenic treatment plus 1 h tempering at 650 ℃. |

| Keywords: | hot die steel deep cryogenic treatment abrasion performance quenching temperature retained austenite hardness |
