The thermal stability and glass forming ability of Cu50-xZr 43Al7Agx (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 ΔTx(=T X-Tg), Trg(=Tg/Tl) and γ(=Tx/(Tg+Tl)), 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.
