Notes:
Hydrogen is considered to be a possible energy source in the coming future. However, ithas been recognized that hydrogen has a detrimental effect on the fatigue strength of metal. Thefatigue crack growth characteristic is an important property for the integrity assessment of hydrogenutilization machine. In this report, the effect of hydrogen on the fatigue crack propagationcharacteristic was studied using low alloy steel, carbon steels and A286 alloy. Especially in this study,very short pre-cracked specimen as small as 0.03 mm deep was used and the near threshold fatiguecrack behavior was studied. As a result, materials whose Vickers hardness was higher than 300 werefound to be susceptible to absorbed hydrogen
