In this paper, the results of creep-rupture, fatigue, and creep-fatigue tests obtained for the weldments of modified 9Cr-1Mo steel at elevated temperatures (500, 550 and 600 C) are presented. The fatigue properties of weldment, such as fatigue life, stress-strain response, and failure location, can be predicted well by the bi-element model of base metal and weld metal which have their corresponding mechanical properties. Furthermore, the creep-fatigue life of weldment can be predicted well by the bi-linear model.
