Experimental evaluation and modeling of fatigue of a 316L austenitic stainless steel in high-temperature water and air environments

Austenitic stainless steels is used in many components of nuclear power plants, particularly in the pipes of cooling systems. Owing to power transients and to start-ups and shutdowns, these components are subjected to thermo-mechanical loadings (low-cycle ...
