Abstract

A nanostructured bulk metallic alloy reinforced by um-ceramic particles was prepared using nanoprecipitation in glassy matrix phase of a Cu ₆₀Zr₃₀Ti₁₀ bulk glassy alloy containing 10 vol% ZrC dispersoids by a heat treatment. Structure of the matrix consists of a nanocrystalline phase less than 5 nm in diameter and a small amount of the residual glassy alloy phase. Composite effects of the nanoprecipitates and ZrC dispersoids on the mechanical properties of the CuooZrsoTijo bulk glassy alloy were investigated by compressive test at room temperature. Both fracture strength and ductility of the Cu₆₀Zr₃₀Ti₁₀ glassy alloy were improved by μm-ZrC dispersoids at as-cast state. This composite material after heat treatment showed lower ductility but higher fracture strength due to nanoprecipitation of the glassy matrix.
