The Activation and Hydrogen Sorption Characteristics of Zr57V36Fe7 Alloy and its Constituent Phases
Zr57V36Fe7 alloy is widely used as non-evaporable getter(NEG) material because of its high sorption properties for various gases and relatively low activation temperature. Structurally, it is composed of two phases i.e. AB2 type cubic Laves and hexagonal α-Zr solid solution. The activation and sorption behavior of Zr57V36Fe7 alloy getter was explained in terms of its component phases. It was found that the activation of the alloy is stimulated by the presence of cubic-Zr(V, Fe)2 phase. It is believed that once activated α-Zr solid solution enhance, the sorption of hydrogen.
