摘要：

This study is concerned with the creep damage evaluation for the welded joint of modified 9Cr-1Mo steels. A finite element prediction method based on ductility exhaustion approach has been proposed. Degradation of creep ductility under multi-axial stress state has been formulated from the experimental results of notched bar specimens for the base metal and the fine-grained heat affected zone, and has been taken into the damage model. Creep test of welded joint specimen of modified 9Cr-1Mo steel has been conducted to confirm the accuracy of the damage evaluation method. It has been concluded that the predicted trend of creep damage has good agreement with the experimental results, but the predicted rupture time become longer than the experimental results of rupture time.
