説明
Fatigue tests under controlled experimental humidity were conducted to reveal the effects of constituent elements on hydrogen embrittlement resistance of 6061 aluminum alloy. Under a humidified air condition hydrogen atoms are generated through a reaction between successively exposed aluminum alloy surface and vapor water, and then the hydrogen embrittlement of the alloy can be studied by controlling experimental humidity. Although a standard 6061 alloy showed no hydrogen embrittlement under humidified air condition, Al–Mg–Si ternary alloy of the same Mg and Si content as the standard 6061 alloy had a much shorter fatigue life under humidified air condition than under dry nitrogen gas condition, and showed significant hydrogen embrittlement. The higher hydrogen embrittlement resistance of the 6061 alloy than the ternary alloy was attributed to constituent elements of Cu and Cr in the 6061 alloy. The observation of fatigue fracture surfaces suggested that Cu addition decreased hydrogen embrittlement sensitivity of the alloy itself and Cr addition decreased sensitivity for intergranular cracking through refinement of the grain structure.
