Strain hardening effect of CF8M stainless steel in the environment fatigue test under pressurized water reactor condition

Strain Rate Change From 0.04 to 0.004%/S in an Environmental Fatigue Test of Cf8m Cast Stainless Steel

“…A test procedure which was developed to incorporate the CSH into the environmental fatigue test was presented in previous studies [10,11]. A displacement relation formula between the gauge length (R.G., real gauge) and the shoulder length (S.G., shoulder gauge) of the specimen was derived from simultaneously measured displacement data of a preliminary fatigue test in a hot air environment of 315ºC with strain control at the gauge length.…”
