Abstract
Creep crack growth tests on a 1CrMoV steel are presented, covering the aspects of specimen size, geometry and service-like stresses. To cons ider nonstationary loading in modern plants creep fatigue crack growth tests have been started. As test materials a 1CrMoV steel and a modem 9%Cr-steel were used. By means of a comparison of creep crack and cre ep fatigue crack results the effectiveness of the fracture mechanics p arameters K-l, Delta K-l and C could be evaluated.
