Abstract
The only direct attempt to determine the rate of diffusion of hydrogen through solid aluminium, of which we are aware, is described in a paper by Deming and Hendricks, * in which they conclude that aluminium is impermeable to hydrogen at temperatures up to 550° C. Very slow rates of diffusion would not have been detected by the method employed. The solubility of hydrogen in aluminium has been measured by Iwasé, Röntgen and Braun, and Röntgen and Möller.§ No solubility was detected in solid aluminium, but molten aluminium dissolves about 0·1 to 0·2 cc of hydrogen per 100 gm of metal at the melting-point, and the solubility increases with temperature.
