Abstract

Zr₆₃Al₁₀Ni₁₀Cu₁₄ Nb₃ monolithic bulk metallic glass (BMG) and Zr₅₅ Al_8.5Ni_8.5Cu₁₃Nb₁₅ BMG matrix composite containing densely distributed bcc dendritic phase were prepared by copper mould casting. The ductility of the dendritic phase was verified by nanoindentation tests. However, the composite samples exhibit relatively lower yield strength and no plastic strain under room temperature compression test. Microstructural characterization and fractography studies reveal that the simultaneous formation of quasicrystalline phase on the outermost region of the composite results in the brittleness of the composites. © 2005 Elsevier B.V.
