In order to investigate the effect of hydrogen on fatigue crack growth property in newly developed Fe-15Mn-based austenite alloy, fatigue crack growth tests were conducted with non-charged specimens in air, non-charged specimens in 0.7 MPa hydrogen gas, and hydrogen charged specimens in air. As a result, the new alloy used in this study was clarified to show that of the fatigue crack growth behavior is not accelerated by hydrogen charging.
