The structure, the hydrogen capacity and the hydrogen desorption behavior of hydrogenated Ti 3Al-based alloys substituted with Nb, Mo, Pd, Ta and W were investigated by XRD and a hydrogen analysis with the aim of selecting effective elements to improve the hydrogen absorption-desorption properties of a binary Ti 3Al alloy. The relation between the hydrogen capacity and the 50% hydrogen desorption temperature was plotted in the diagram obtained in the previous work. Mn, Co, Ni and Nb were selected to be effective elements to reduce the hydrogen desorption temperature, although they gave rise to reduction in the hydrogen capacity.
