“…On the other hand, in the 30% and 60% prestrained specimens, cracks were generated from corrosion pit (see Fig.6). Since martensite phase is inferior to austenite phase in corrosion property [13], it seems that anodic dissolution took place in the 30% and 60% prestrained specimens that contain a significant amount of martensite phase. This suggests that the corrosion fatigue behavior of SUS304 is affected by environmental sensitivity of martensite phase.…”

The present paper describes the effect of prestrain on fatigue behavior in type 304 stainless steel. Rotating bending fatigue tests have been conducted in laboratory air and in 3%NaCl solution using specimens subjected to the tensile-prestrains of 15%, 30% and 60%. A particular attention was paid to the strain-induced martensitic transformation during stress cycling. The fatigue strength of the prestrained specimens increased with increasing prestrain in laboratory air, but decreased significantly in 3%NaCl solution compared with in laboratory air. The strain-induced martensitic transformation occurred in the prestrained specimens, and martensite phase increased with increasing prestrain and with stress cycling at the fatigue limit stress in the 30% and 60% prestrained specimens. The coaxing effect took place remarkably in the unprestrained specimen, but decreased with increasing prestrain. The increase in fatigue strength of the prestrained specimens in laboratory air and the coaxing effect were attributed to both work hardening and the strain-induced martensitic transformation, where the contributions of the former and the latter decreased and increased with increasing prestrain, respectively. Since corrosion pits were observed at the crack initiation site in the large prestrained specimens, the decrease in fatigue strength in 3%NaCl solution was due to larger environmental susceptibility of martensite phase.

“…Other considerations for dissolution-based mechanisms include the possibility that the dissolution rate is promoted by the presence of hydrogen (or vacancies) ahead of crack tips [115], and that hydrogen incorporated into fi lms at crack tips affects their stability [116,117] and could affect other properties, e.g. fracture strain.…”

“…It has been shown that hydrogen increases the corrosion rates of precharged austenitic stainless steels and carbon steels [13][14][15]. In austenitic stainless steels, hydrogen was found to promote anodic dissolution, to decrease the stability of the passive film [16] and to increase pitting susceptibility [17].…”
