摘　　要：通过等温时效试验、恒载荷蠕变试验、电解萃取试验以及X射线衍射试验,得到不同服役阶段材料碳化物相含量以及衍射强度之比,并建立其与服役寿命和Larson-Miller参数P之间的关系。结果表明,Laves相与MX相衍射强度之比R与L-M参数P以及寿命消耗比例之间呈线性关系,且线性良好,为后续的寿命预测提供参考。The ratio of carbide phase content to the diffraction intensity was obtained during different periods of service after isothermal aging test,constant-load creep test,electrochemical extraction test and X-ray diffraction(XRD)test,and the relationship between service life and Larson-Miller parameter P was established.The results show that the diffraction intensity ratio(R)between Laves phases and MX phases presents a good linear relationship between parameter P of L-M Equations and life consumption ratio,which provides reference for subsequent life prediction.
