Abstract
Diffusion coefficient and solubility of hydrogen in commercial pure solid aluminum of 2N(99.7 mass%) were measured by means of the ordinary desorption method, and they were compared with those of high-purity 4N aluminum. A variety of distribution of intermetallic compound particles did not essentially influence the hydrogen diffusivity, but grain boundaries did affect the diffusion. Hydrogen was affected by «fast diffusion» along a straight and long grain boundary, and «trapping» at perhaps a cornered or crossed grain boundary junction. The grain boundary cross effect on the hydrogen diffusivity was also confirmed for 2N aluminum as with 4N aluminum
