Abstract

The effects of Al addition on structures and protium absorption-desorption properties of Ti-Cr alloys were investigated. It was found that 1 at% Al addition is effective for improvement of protium storage capacity. The BCC phase increases with increasing Al content in TiCr-Al alloys. It is generally well known that plateau pressure of the protium storage alloys, e.g. Ti-Cr-V and Ti-Fe-V alloys, increases with decreasing lattice constants, however, the plateau pressure of the Ti-Cr-Al alloys increases with increasing lattice constants, namely increasing Al content.
