摘要：

The structural changes in Pd and Pd-Ru alloys induced by the repeated absorption-desorption of hydrogen have been studied. It is found that absorption-desorption cycles produce structural changes in Pd whereas the addition of small amounts of Ru inhibits these hydrogen-induced changes. The experimental results show that bulk hydrogen absorption occurs in Pd, while hydrogen surface adsorption becomes dominant over bulk absorption, in the Pd-Ru alloy.© 1995 American Institute of Physics.
