Abstract

The Influence of the nano-crystallization by annealing of a Cu ₆₀Zr₃₀Ti₁₀ bulk glassy alloy and of a Cu ₆₀Zr₃₀Ti₁₀ bulk glass containing 10 vol% ZrC dispersoids on its mechanical properties was investigated. By annealing at the onset temperature of the glass transition, fine particles of less than 10 nm in size precipitated in glassy matrix phase. The mechanical properties of the Cu₆₀Zr₃₀Ti₁₀ and of the Cu₆₀Zr ₃₀Ti₁₀/10vol% ZrC dispersoids alloys were enhanced by annealing. By both effects of nano-precipitates and of μm-ceramic dispersoids, mean increase of fracture strength of the Cu₆₀Zr ₃₀Ti₁₀ glassy alloy reached 522 MPa (= 27 % increase).
