Abstract— Tests have been carried out on a 1 Cr-Mo-V steel at 565°C to describe creep crack initiation in two notched geometries. From metallographic observation the initiation times were observed to be approx. 8 and 13% of rupture lives for the sharp slit and blunter notch shapes, respectively. Based on only a few tests a relationship between the initiation time ti and the creep crack parameter J* was found to be of the form ti(J*)0.67= constant.
