Abstract

Fully reversed bending fatigue tests were performed on low carbon steel JIS S10C in hydrogen gas and in nitrogen gas at a low pressure. In nitrogen a crack showed almost the same non-propagating behavior as known in air, while in hydrogen a crack continued to propagate even near 10' cycles at the same testing strain range. In hydrogen gas, a crack showed intermittent growth by coalescing with a new micro-crack generated by slip behavior. This implies that hydrogen could reduce the ability of any factor affecting non-propagation.
