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).
