Notch Effect on the Corrosion Fatigue Behavior of an Austenitic Stainless Steel


Article Preview

The objective of this study is to characterize the influence of notch effect on the high-cycle corrosion fatigue properties of AISI 347 stainless steel in various environments, namely, air, water, NaCl, NaCl plus inhibitor, and H2SO4 solutions. For smooth-surface and semi-circular notch specimens, the rank of fatigue strength in all of the given environments generally took the following order: air ≈ salt water plus inhibitor > deionized water > salt water > sulfuric acid solution. For V-notch specimens, the S-N curves were separated into two groups, i.e. one with air and 3.5% NaCl plus inhibitor and the other with deionized water, 3.5% NaCl and H2SO4. This was attributed to a greater effect of localized acidification occurring at the root of V-notch as compared to the smooth surface and semi-circular notch.
