Regularities of hydrogen interaction with multicomponent Ti(Zr)-Mn-V Laves phase alloys

Titanium- and zirconium-based multicomponent Laves phases deriving from binary TiMn2 and ZrMn2 compounds are one of perspective groups of hydrogen-absorbing alloys for use in various hydrogen storage and energy conversion devices. Extensive systematic study of hydrogen sorption properties of nonstoichiometric alloys of Ti(Zr)-Mn-V system was performed in this work. Results of X-ray, neutron diffraction and PC-isotherm investigations are presented. Some useful regularities were found, which can be useful in prediction of hydrogen sorption properties of ternary alloys.
