Abstract

Effect of oxygen on the phase formation and thermal stability of Zr₅₀_·₇₅(Cu₉₀Ni₁₀)₄₀_·₂₅Al₉ bulk metallic glass (BMG) has been systematically studied. Our results show that τ₃ phase (Zr₅₀Cu₂₉Ni₂Al₁₉ intermetallics) can be formed when the oxygen level reaches 350 ppm and its morphology changes from an undeveloped dendritic to dendritic structure with increasing oxygen content. It is demonstrated that oxygen is mainly concentrated in τ₃ phase. Microstructure characterization indicates that τ₃ phase possesses a face-centered cubic structure and its lattice parameter increases with increasing oxygen content. These findings would aid the development of Zr-based BMGs with industrial grade materials for commercial application.
