The effect of Al substitution on the hydrogen absorption in Zr(AlxV1 x)(2), x = 0, 0.1, 0.2, 0.5, has been examined at the pressure range 10 (4)-1000 Torr for temperatures between 400 and 700 degrees C. The increasing content of Al destabilizes the bulk hydrogen absorption across the pseudobinary Zr(AlxV1 x)(2) intermetallic compounds. This behavior is opposed to the Al effect in other well-known hydrogen absorbing systems like LaAlxNi5 x, Zr(AlxCo1 x)(2), Zr(AlxFe1 x)(2). This difference is discussed in view of the various factors that determine hydrogen absorption in intermetallic systems.
