In situ X-Ray diffraction study of hydrogen sorption in V-rich Ti-V-Cr bcc solid solutions

Abstract Alloying of vanadium with a combination of titanium and chromium has been investigated in this study. Hydrogenation/desorption of several alloys under similar experimental conditions has been performed and sequentially followed by means of in situ X-Ray powder diffraction. This latter technique has been used as a probe of formation or decomposition of hydrides. Geometrical effects are discussed and account for the observed similarities of the sorption properties.
