► Bulk Cu50Zr40Ti10 amorphous alloy composites were successfully fabricated. ► The electrical conductivity of the BAA composites is dramatically improved. ► The thermal diffusivity of the BAA composites is dramatically improved. ► The BAA composites exhibit a macroscopic plasticity. Cu50Zr40Ti10 amorphous alloy powder and Cu60Zr30Ti10 plate-like ultrafine alloy powder were prepared by gas-atomization and ball-milling methods, respectively. Cu50Zr40Ti10 bulk amorphous alloy (BAA) composites reinforced by Cu60Zr30Ti10 alloy powder were fabricated by hot pressing method. The matrix of the composites remains a fully amorphous phase after consolidation process. The Cu50Zr40Ti10 BAA composites exhibit improved plasticity and dramatically improved electrical and thermal properties by the Cu60Zr30Ti10 powder addition. However, the density and compression strength of the BAA composites decrease with the increasing amount of Cu60Zr30Ti10 alloy powder.
