HYDROGEN ABSORPTION AND MODULATED STRUCTURE IN TI-V-MN ALLOYS

In order to apply hydrogen-absorbing alloys to new energy carrier uses , such as hydrogen storage tanks or Ni-MH batteries, a drastic increas e in the hydrogen capacity of these alloys is required. For years, int ermetallic compounds or single-phase alloys have been studied as hydro gen-absorbing materials. New approaches to alloy design, relating to m ultiphase alloys, are proposed and verified. These approaches help to identify a new structure on a multiphase alloy. As a result, a new hyd rogen-absorbing alloy, consisting of a nano-structure having a large h ydrogen capacity and good desorbing properties, was found.
