Ti-V-Cr BCC solid solutions are known to absorb a high amount of protium. But, relations of their microstructures with their protium absorption-desorption properties are not systematically studied. The purpose of this study is to clarify the effects of V content and heat-treatment on the protium absorption-desorption properties of Ti-(0-35)at%V-Cr alloys. Addition of V to Ti-Cr alloys was effective in forming a BCC phase. However with decreasing V content, a Laves phase was formed and an effective protium capacity decreased. Annealing at 1573 K was effective to flatten the plateau region and enlarge the effective protium capacity. A Ti-10V-55.4Cr alloy, which contained a Laves phase in the as-cast state, became a BCC single-phase after annealing over 1573 K. Even though the alloy contains only 10 at%V, this heat-treated alloy showed an effective protium capacity of 2.5 mass%H.
