Hydrogen storage in Ti-based quasicrystal powders produced by mechanical alloying

Ti-based quasicrystals belong to the second largest group of the stable quasicrystals, showing attractive properties as hydrogen storage materials. This paper summarizes our recent research results on hydrogen absorption and desorption properties of the Ti–Zr–Ni and Ti–Hf–Ni quasicrystals and the related phases produced by a combination of mechanical alloying and subsequent annealing.
