Abstract
A 10mm cubic specimen cut from a chill-cast Mg-30%Ni-5%Y alloy block was vacuum-heated for 4 h at 873 K and was then examined under optical and electron microscopes to determine structural changes and to identify constituents along from the inside to the outside at the vertical section of the deformed specimen. The specimen was then pulverized for measuring X-ray diffraction patterns, following to hydrogen absorption tests at room temperature and 473 K. As a result, it was deduced that an angular ternary compound existed in hardly visible size and number in the as-cast alloy, but newly produced largely by the vacuum heating and identified as MgNi3Y by EPMA might behave as a catalyst to enhance the hydrogen absorption rate at room temperature.A similar experiment was also performed on Mg-30%Ni-10%Ho alloy as a reference.
