Effect of Mo additive on hydrogen absorption of rare-earth based hydrogen storage alloy

Abstract The aim of this study is to reveal the role of substitution of the host element in RE-based AB 5 -type alloy by Mo. For this purpose on the base of Mo-free alloy a number of VAR-melted composites were prepared. The influence of Mo additive was studied by comparison of their P – C – I characteristics with the data obtained from XRD analysis. Predicted earlier the positive influence of substitution of the host element in AB 5 -type alloys by metal with increased atomic number Z on their hydrogen absorption capacity in the main was confirmed.
