A new way of designing bulk metallic glasses in Cu–Ti–Zr–Ni system

This paper presents a new way of designing bulk metallic glasses in Cu–Ti–Zr–Ni system based upon binary deep eutectic. By conventional copper mold casting method, these alloys can be quenched into single amorphous structure with the diameter ranging from 3 to 5 mm. Experimental results show that among the alloy series designed Cu52.55Ti30.05Zr11.4Ni6 and Cu53.1Ti31.4Zr9.5Ni6 possess the relatively higher Trg of 0.603 and 0.598, respectively, which contribute to their good glass forming ability, and Cu52.55Ti30.05Zr11.4Ni6 exhibits a relatively higher Tg (694 K) and ΔTx (52 K), which indicate its good thermal stability.
