Change in primary phase from icosahedral quasicrystal to fcc Zr2Ni by mechanical disordering in Zr–Al–Ni–Cu–Pd glassy alloy

Change in the primary crystallization from a single icosahedral quasicrystalline phase into the fcc Zr2Ni phase by mechanical disordering was investigated in a melt-spun Zr65Al7.5Ni10Cu12.5Pd5 glassy alloy. The transition of the primary phase is attributed to the mechanical strain induced in the icosahedral local structure in the glassy state.
