    Notes: Aluminum alloy is one of the candidates for the liners of compressed hydrogen tank mountedto fuel cell vehicles. It is crucial to elucidate the behavior of hydrogen in the alloy sheet with one sidebeing exposed to hydrogen gas. In the present work, using the hydrogen microprint technique, in 6061and 7075 aluminum alloy sheets, relationship between hydrogen pressure and the molar quantity ofhydrogen emitted from the inside has been investigated. Under any pressure, the quantity of emittedhydrogen is about 10 times smaller in the 7075 alloy than in the 6061 alloy. This indicates that theamount of hydrogen atoms accumulating in the 7075 alloy may be much larger than that in the 6061alloy

    Notes: High-magnesium Al-Mg alloys are known to be sensitive to stress corrosion cracking involvingenvironmental hydrogen, hydrogen invading from the corrosive environment. In this study, the behavior of theenvironmental hydrogen in Al-6%Mg and Al-8%Mg binary alloy sheets stretched by 10% during exposure to3.5%NaCl solution has been investigated by means of hydrogen microprint technique. Microprint image isobserved on one surface while the other surface is exposed to the solution. In both alloys, the silver particlescorresponding to the sites where hydrogen atoms are emitted from the inside of the sheets are shown on the sliplines. It is shown that the hydrogen atoms are transported with moving dislocations in the alloys
