Notch Sensitivity Effect on Fatigue of Aermet 100 Steel in Air and Salt Water,

Abstract

This study was conducted to characterize the degradation of fatigue life due to notch sensitivity and environmental atmospheres. This degradation effect was compared to previous effects upon the fatigue life behavior of a 300M steel. The test specimens were subjected to constant amplitude tension-tension (R=0.1) fatigue testing in laboratory air and a salt water environment. Two notch depths were produced to simulate machining damage, while the two notch radii tried to bound the stress states from this induced machining damage.
