Abstract

The present letter reports the formation of the icosahedral phase during crystallization of amorphous Zr65−x Cu27.5 Al7.5 Ox (x = 0.43% and 0.82%) alloys. Three-dimensional atom probe studies have revealed that the quasicrystalline phase is enriched in oxygen. This, together with the fact that no icosahedral phase forms at low oxygen level (0.14%), clearly establishes that the quasicrystallinephase in Zr-based metallic glasses is stabilized by oxygen.
