Abstract

Formation and mechanical properties of Cu-Zr-Al-Sn bulk metallic glasses were investigated. The glass-forming ability of Cu₅₀Zr₅₀ alloy is significantly improved with addition of Al, and the critical diameter for glass formation increases from 2 to 7 mm for Cu_46.25Zr _46.25Al_7.5 alloy. Furthermore, the critical diameter is slightly increased to 8mm by substituting 1 at% Sn for Zr of Cu _46.25Zr_46.25Al_7.5 alloy. The bulk glassy Cu_46.25Zr_46.25Al_7.5 alloy exhibits a limited plasticity of about 1.2% to failure under compression and the plasticity is effectively enhanced due to the addition of Sn, about 4.1% for bulk glassy Cu_46.25Zr_45.25Al_7.5Sn₁ alloy.
