Understanding nano quasicrystalleve phase formation in Zr based alloys

Nano icosahedral phase formation was observed in a number of Zr-based metallic glasses. This present paper reviews the present understanding on the nanoquasicrystalline phase formation in Zr-based alloys. The results indicate that oxygen stabilizes quasicrystalline phase. A large negative enthalpy of mixing and/or existence of Frank-Kasper-type phases.
