Creep crack growth experiments on Type 304 stainless steel and Cr-Mo-V steel were conducted with special emphasis on the detail observation of the crack growth and deformation behavior during deformation rate and the modified J-integral. J' were very high as compared with whose under steady-state creep conditions and decreased sharply with time, and that localized slops at grain boundaries in from of a crack tip developed. The crack growth rate was relatively low in this stage. In the latter half stage crack growth was controlled mainly by the coalescence of micro-cracks initiated at grain boundaries with a main crack and the crack growth rate was approximately given as a sole function of J'. These phenomena were interpreted by considering the effect of small-scale creep as well as that of damage accumulation.
