Crack Propagation under Fatigue-Creep Conditions and Fractography

TLDR: In this paper, the crack propagation of a 304 stainless steel under repeated load at elevated temperatures was examined using specimens of different size to clarify the successful correlating parameter, and the results were discussed in the light of electron fractography.

Abstract: The crack propagation of a 304 stainless steel under repeated load at elevated temperatures was critically examined using specimens of different size to clarify the successful correlating parameter, and the results were discussed in the light of electron fractography. The crack propagation rate at 250 and 500°C where creep is not significant in this material was correlated with the stress intensity
