Study on AE properties of A6061-T6 alloy for high-pressure hydrogen gas container during tensile and fatigue testing (Influence of grain size)
A6061-T6 alloy has been used in the liner material of high-pressure hydrogen gas storage container that is mounted on Custom Shaped Pillow a fuel cell vehicle.The degradation of the properties such as strength, toughness and hydrogen embrittlement resistance, etc., has been pointed out, because the grain structure of the mouthpiece part of the line
