A combined experimental and computational study is carried out on creep crack growth in X20CrMoV 12 1 steel and its weld joint. Crack growth tests are conducted on compact specimens at 545°C. For weld specimens, the crack propagates in the heat-affected zone parallel to the fusion line. It is found that correlates crack growth rates satisfactorily under the loads used in the test not only for base metal specimens but also for weld specimens. An elastic-plastic-steady-state creep analysis of crack growth is performed using a finite element code. Calculated load point displacement rates agree with experimental measurements during steady-state crack growth. The creep zone is asymmetric, and it becomes more so in weld specimens as the crack propagates. Yet the mode II effect appears to be insignificant.
