Low-cycle creep-fatigue tests of the dissmilar metal electron beam welded joint between A387Gr. 22 steel and SUS 405 steel were carried out under the strain-controlled cycling over the welded joint at 873K. It was shown that the creep-fatigue life of the dissmilar metal welded joint was significantly shorter than those of the base metals. This resulted from the strain concentration on the SUS 405 side with lower deformation resistance. It was also found that the hardness distribution was one of the important measures which reflect the strain distribution. Furthermore, the predicting method of creep-fatigue life for dissmilar metal welded joints was proposed by applying the strain range partitioning approach. The predicted lives were in good agreement with the experimental results.
