Abstract

Icosahedral (i) quasicrystals, which have a new type of translational long-range order and display a non-crystallographic rotational symmetry, were first observed in the Al-Mn alloy. Since the discovery of the Ti-Zr-Ni i quasicrystal phases (i-phases), studies on their hydrogen storage properties have been extensively conducted for not only their industrial applications as hydrogen storage media, but also scientific interest in their local structures, using a proton as a probe. The Ti/Zr-based i-phase has been mainly produced either by rapid-quenching or annealing the amorphous phase obtained by mechanical alloying (MA). We have systematically studied hydrogenation of the Ti/Zr-based amorphous and i-phase powders synthesized by MA and subsequent annealing respectively. In this chapter, we have reviewed the recent progress in ...
