Abstract

A novel centimeter-sized Ti-based bulk metallic glass (BMG) was developed by the addition of Ag in the ternary Ti₄₁Zr₂₅Be ₃₄ glassy alloy. By replacing Be with Ag, the glass forming ability (GFA), the yield strength, and the supercooled liquid temperature of the quaternary Ti41Zr25Be34-xAgx (x=2, 4, 6, 8 at.%) glassy alloys have been obviously enhanced. Among the developed Ti-Zr-Be-Ag alloy systems, the Ti ₄₁Zr₂₅Be₂₈Ag₆ alloy possesses the largest critical diameter (Dmax) of 10 mm, while the yield strength is also enhanced to 1961 MPa, which is much larger than that of Ti₄₁Zr ₂₅Be₃₄ (1755 MPa) alloy. The experimental results show that Ag is an effective element for improving the GFA and the yield strength of Ti-Zr-Be glassy alloy.
