Conclusions 1. An x-ray structural analysis has shown that the critical crack opening and the size of the plastic zone for the middle section of the creep crack growth diagram show little change. At the same time, the critical crack opening at the transfer region from the second to the third section of the curve is significant. 2. In the first section of the DCG ductile dimplelike failure predominates accompanied by a high degree of material break up at the crack tip. In the second section of the DCG there is intergranular cracking and the primary mechanism of failure is the coalescence of the main crack with secondary microcracks which have initiated and grown at some distance ahead of the crack front.
