Preparation of (Ti0.45Cu0.378Zr0.10Ni0.072)100−xSnx bulk metallic glasses

The quinary alloys of Ti–Cu–Zr–Ni–Sn, (Ti0.45Cu0.378Zr0.10Ni0.072)100−xSnx (x = 0, 2, 4, 6, and 8 at.%), have been prepared and studied. The (Ti0.45Cu0.378Zr0.10Ni0.072)100−xSnx (x = 0, 2, 4, 6) bulk glassy rods can been prepared by copper-mold casting. Among these glassy alloys, the (Ti0.45Cu0.378Zr0.10Ni0.072)98Sn2 shows better glass-forming ability than others. Thermal analysis results show that the supercooled liquid range of the Ti–Cu–Zr–Ni glassy alloy has been increased with the addition of Sn. In addition, the as-prepared (Ti0.45Cu0.378Zr0.10Ni0.072)98Sn2 glassy alloy exhibits yield strength and fracture strength of 2260 and 2650 MPa, respectively, together with a compressive plastic strain of 7.6%. The results show that the quinary Ti–Cu–Zr–Ni–Sn bulk glassy alloy possesses good mechanical properties.
