Titanium alloys are widely used in various areas, particularly in medical and dental industries, due to their remarkable properties. Still, the optimum cutting conditions for titanium alloys are under consideration. Ti alloyed with Cu has been reported to provide unique properties such as good mechanical performance, good biocompatibility, acceptable corrosion resistance, and relatively lower melting point. The properties of Ti-Cu alloys mentioned above are sensitive to microstructure. They are highly dependent on microstructural characteristics such as the formation, growth, and morphological features of intermetallics and precipitates, dependent on the amount of Cu and the manufacturing techniques employed. This study strives to scrutinize the effect of manufacturing paths on the microstructural properties of Ti-Cu alloys. To this end, prevalent fabrication procedures for Ti-Cu binary system, from casting and powder metallurgy to semi-solid metal processing and additive manufacturing, are discussed. Finally, the challenges, opportunities, merits and demerits of each technique, and future perspective are addressed.

钛合金因其卓越的性能而广泛用于各个领域，特别是医疗和牙科行业。尽管如此，钛合金的最佳切削条件仍在考虑之中。据报道，与 Cu 合金化的 Ti 具有独特的性能，例如良好的机械性能、良好的生物相容性、可接受的耐腐蚀性和相对较低的熔点。上述Ti-Cu合金的性能对显微组织很敏感。它们高度依赖于微观结构特征，例如金属间化合物和沉淀物的形成、生长和形态特征，取决于铜的量和所采用的制造技术。本研究旨在研究制造路径对 Ti-Cu 合金微观结构性能的影响。为此，讨论了从铸造和粉末冶金到半固态金属加工和增材制造的 Ti-Cu 二元系统的流行制造程序。最后，讨论了每种技术的挑战、机遇、优点和缺点以及未来的前景。
