Abstract

The effect of Al substitution on the hydrogen absorption in Zr(Al xV 1-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 °C. The increasing content of Al destabilizes the bulk hydrogen absorption across the pseudobinary Zr(Al xV 1- x) 2 intermetallic compounds. This behavior is opposed to the Al effect in other well-known hydrogen absorbing systems like LaAl xNi 5-x, Zr(Al xCo 1- x) 2, Zr(Al xFe 1-x) 2. This difference is discussed in view of the various factors that determine hydrogen absorption in intermetallic systems.
