摘要

钛（Ti）的成本、强度和延展性之间的权衡阻碍了钛工业应用的发展。本文采用低成本的高氧氢脱氢（HDH） Ti和流态化改性的Cu粉末，通过增材制造（AM）成功制备了Ti-Cu合金。随着Cu和氧的加入，Ti-Cu合金的强度与纯Ti相比有了明显的提高。通过XRD、SEM、EBSD和TEM对Ti-Cu合金的微观组织进行了观察。本研究揭示了Ti-Cu合金的强化和增韧机制。晶粒细化、固溶强化和纳米Ti2Cu相的分散性是其优异的力学性能的主要原因。该研究为3D打印低成本、高性能金属提供了有益的指导。

Achieving low-cost, and high-performance titanium-copper alloys by additive manufacturing

The trade-off between the cost, strength and ductility of titanium (Ti) hinders the development of the industrial applications of Ti. In this work, Ti-Cu alloys were successfully produced via additive manufacturing (AM) by employing low-cost hydrogenation dehydrogenation (HDH) Ti with high oxygen content and Cu powders modified through fluidization. With the addition of Cu and oxygen, the strength of Ti-Cu alloys exhibits a significant enhancement compared to pure Ti. The microstructure of the Ti-Cu alloys was observed through XRD, SEM, EBSD, and TEM. The underlying strengthening and toughening mechanisms of Ti-Cu alloys were uncovered in this study. The excellent mechanical properties may be attributed to grain refinement, solid solution strengthening, and dispersion of nanoscale Ti₂Cu phase. This study provides a useful guidance for 3D printing low-cost, and high-performance metals.
