氢蚀对15CrMo钢疲劳裂纹扩展寿命的影响

Influence of Hydrogen Attack on Fatigue Crack Spread Life of 15CrMo Steel

对 1 5Cr Mo钢在氢蚀环境下和疲劳裂纹行为作了研究 ,重点考察了不同温度、压力和时间等情况下的扩展特性 ,并找出了对

The fatigue crack spread behavior of 15CrMo steel under hydrogen attack environment is studied. The investigation emphasis is laid on the spread behavior under different temperature, pressure and time. The influence trend on the coefficient of Paris Equation is also found.
