AbstractMost common in Al-3d transition metal(TM) alloys, icosahedral quasicrystals (i-phase) are also found frequently in Ti/Zr-TM alloys. The Ti-TM-Si-O quasicrystals are metastable, produced only by rapid quenching, and are extremely disordered. In contrast, Ti-Zr-Ni i-phases are well ordered and stable, produced by relatively low temperature annealing, nearly 300°C below the melting temperature. Important for both basic and practical reasons, Ti/Zr-based quasicrystals can absorb significant quantities of hydrogen, up to two hydrogen atoms for each metal atom. The formation and structures of these quasicrystals and closely related complex crystal phases are discussed. The hydrogenation properties of these quasicrystals are presented and shown to be competitive with materials in current use for hydrogen storage and battery applications. Results from recent studies using hydrogen as a probe of the local structure of the quasicrystal and crystal approximant are presented.

Storage Properties

The mixed powder method and covering method were adopted to prepare a composite that has hydrogen storage properties. In the experimental process, the alloy phases Mg2Ni and NiTi generated regularly; the penetration of the hydrogen atoms to the material was considered as the adsorption of the material to the hydrogen atoms; the original thermodynamic equation was edited; the crystal phases were optimized by adjusting the parameters about the material composition and gas concentration, so that providing advantageous channels of the hydrogen atoms in and out to improve the hydrogen storage properties. The results showed that integer multiples adjustment to trace element Ti could make hydrogen storage properties maximizing optimize and have controllability for the capacity and rate of hydrogen storage according to the newly editing equation. The innovation was to edit out equation that can improve the hydrogen storage properties through adjusting three parameters of trace element Ti, adsorption and penetration to find the most optimal condition improving the hydrogen storage properties.
