摘　　要：试验研究了经不同温度正火和回火后 ,0 .14C 1.2 5Cr 0 .5Mo钢中M3C、M2 3C6 碳化物中Cr、Mn、Mo的含量以及充氢前后淬火和回火温度对钢的力学性能的影响。结果得出 ,经 890～ 980℃正火、6 70～ 710℃回火 ,该钢具有良好的抗氢蚀能力 ,5 2 0～ 6 2 0℃回火后试样充氢后的强度明显下降。The Cr, Mn and Mo content in M\-3C and M\- 23C\-6 carbides in steel 0.14C-1.25Cr-0.5Mo after quenching and tempering at different temperature and the effect of quenching and tempering temperature on mechanical properties of the steel with and without hydrogen attack have been tested and investigated. The results are obtained that with 890～980 ℃ normalizing and 670～710 ℃ tempering, the steel has excellent hydrogen attack resistance and with 520～620 ℃ tempering the hydrogen attack resistance of steel decreases obviously.
