Abstract

The thermal stability and glass forming ability of Cu_50-xZr ₄₃Al₇Ag_x (x=0, 1, 3, 5, and 7) bulk metallic glass alloys have been investigated. The glass forming ability in the Cu-Zr-Al-Ag alloys increased proportionally to the Ag content and show good correlations with thermal parameters such as ΔT_x(=T _X-T_g), T_rg(=T_g/T_l) and γ(=T_x/(T_g+T_l)), For the Cu ₄₃Zr₄₃Al₇Ag₇ alloy, fully amorphous rods of 8 mm diameter were successfully fabricated by copper mold casting. Mechanical tests on this composition revealed also remarkable properties with compressive strength around 2000 MPa and large ductility.
