摘要：

The protium absorption-desorption properties of Ti-V-Cr-Mn alloys were studied by varying the contents of Mn, Ti and V in the alloys. It was found that Mn addition of <10 at% was effective in improving the slope of the plateau region without any reduction of the protium absorption-desorption capacity. For Ti-V-Cr-Mn alloys, the alpha-Ti phase, which does not contribute to the protium storage capacity, appeared along grain boundaries during heat treatment. The formation of the alpha-Ti phase was found to be suppressed by reducing the Ti content and increasing the V content. By inhibiting the appearance of the alpha-Ti phase along the grain boundary, the protium absorption-desorption capacity of Ti-xV-Cr-Mn (x=45, 55; Ti/Cr/Mn=24:31:10) heat-treated alloys exhibited 2.7 mass% H, the highest value reported so far.
