    Abstract

    In this paper, the life assessment procedure for weldment of high Cr steel (ASME Code Case P91 and P92) was reported as the Japanese results for the VAMAS Project and JSPS 120 Committee. This report indicates that in order to predict the total fracture life for weldment, it is important to clarify the incubation process and path on a structural mechanical basis in order correctly determine the incubation time of creep crack growth.
