Abstract
In order to investigate the effect of hydrogen environment on fatigue crack growth
characteristics of a low carbon steel JIS S10C, fatigue crack growth tests were conducted in a low
pressure hydrogen gas environment. Fatigue crack growth rate in hygrogen gas is higher than that in
nitrogen gas. It seems that a crack in the range of low growth rate prefers to propagate along the
grain boundaries under hydrogen environment while in the range of high growth across the grains
accompanied by brittle striation patterns or river patterns. It is important to clarify how hydrogen
affects the crack growth behavior of different stages of crack growth.
