本文提出了一种基于二元深共晶的Cu-Ti-Zr-Ni系大块非晶合金设计的新方法。用常规的铜模铸造方法，这些合金可以淬火成直径为3 ~ 5 mm的单一非晶组织。实验结果表明，在所设计的合金系列中，Cu52.55Ti30.05Zr11.4Ni6和Cu53.1Ti31.4Zr9.5Ni6具有较高的Tg（0.603）和Δ Tx（52 K），分别为0.598和0.603，这是它们具有良好的非晶形成能力的主要原因，其中Cu52.55Ti30.05Zr11.4Ni6具有较高的Tg（694 K）和ΔTx（52 K）。表明其具有良好的热稳定性。
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 5mm. Experimental results show that among the alloy series designed Cu52.55Ti30.05Zr11.4Ni6and Cu53.1Ti31.4Zr9.5Ni6possess the relatively higher Trgof 0.603 and 0.598, respectively, which contribute to their good glass forming ability, and Cu52.55Ti30.05Zr11.4Ni6exhibits a relatively higher Tg(694K) and ΔTx(52K), which indicate its good thermal stability.
