Enhancement of the glass forming ability of Cu− Zr− Al alloys by Ag addition
Metals and materials International, 2004•Springer
The thermal stability and glass forming ability of Cu 50-x Zr 43 Al 7 Ag 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 xT g), T rg (= T g/T 1) and γ (= T x/(T g+ T 1)). For the

Abstract
The thermal stability and glass forming ability of Cu50-xZr43Al7Agx (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(=Tx-Tg), Trg(=Tg/T1) and γ(=Tx/(Tg+T1)). For the Cu43Zr43Al7Ag7 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.
