研究了不同固溶与时效处理对45Cr14Ni14W2Mo钢组织和性能的影响。根据试验结果分析,在1170℃固溶处理保温60 min(水冷)+760℃时效处理(保温5 h)空冷,可获得良好的性能,能够满足内燃机气阀用钢及合金棒材的标准要求。
The effects of different solution and aging treatments on microstructure and properties of 45Cr14Ni14W2Mo steel were studied. According to the analysis of the test results, good performance can be obtained by air cooling at 1170 ℃ for 60 min (water cooling) + 760 ℃ aging treatment (holding for 5 h), which can meet the standard requirements of valve steel and alloy bar for internal combustion engine.
