Abstract

Glass formation and mechanical properties of Zr-Al-Co-Cu-Ag bulk metallic glasses (BMGs) were investigated. The glass-forming ability (GFA) of Zr ₅₅Al₂₀Co₂₀Cu₅ alloy is significantly improved with minor addition of Ag, indicating by the impressive increase of the critical diameter of glass formation from 5 mm for Zr₅₅Al ₂₀Co₂₀Cu₅ to 16 mm for (Zr _0.55Al_0.20Co_0.20Cu_0.05) ₉₇Ag₃ and (Zr_0.55Al_0.20Co _0.20Cu_0.05)₉₅Ag₅ alloys. The Zr-Al-Co-Cu-Ag BMGs exhibit high compressive strength of 2160-2280 MPa and distinct plasticity of 0.6-2.5%. The Zr-based BMGs with outstanding GFA and mechanical properties as well as low-level cytotoxicity elements are expectative for industrial and biological applications.
