 note = {application/pdf, As a step to understand the kinetics and mechanisms of hydrogen ab/desorption by/from hydrogen storage materials, alloying effects on these processes were studied with mass analyzed thermal desorption spectroscopy, by using a conventional high vacuum system. A binary alloy system of Zr-Al was selected as a model, and deuterium was used as working gas. It was found that the absorption rate of deuterium is proportional to the half power of deuterium gas pressure, and this is remarkably in contrast with other Zr-based alloys such as Zr-Ni and Zr-V-Fe, which obey the first order kinetics. On the other hand, the desorption process obeyed the second order kinetics with respect to the amount of absorbed deuterium atoms, which resemble to other Zr-based alloys. The activation energies for both the absorption and desorption processes were caused to be lowered by increasing the Al content in the alloys. It was also found that the heat of deuterium (hydrogen) solution decreased by increasing Al composition. The ab/desorption mechanisms and alloying effects were discussed in detail by assuming that changes take place in potential surfaces with alloy composition, Article},
