A new class of titanium alloys developed for additive manufacturing

该项目旨在开发一种新的（Ti-Cu）基合金，具有高强度，高韧性和高抗氢脆性，专门用于增材制造（AM）。本项目期望产生金属AM过程中动态温度场的晶粒细化和相变的新知识，并解决AM Ti部件的共同弱点-强机械各向异性和低疲劳寿命。预期成果包括一整套针对苛刻应用的AM（Ti-Cu）基合金加工图。这将通过提供更好的耐用性、可持续性和成本效益，为航空航天、海洋和生物医学行业带来重大利益。

This project aims to develop a new class of (Ti-Cu)-based alloys featuring high strength, high toughness, and high hydrogen-embrittlement resistance specifically for additive manufacturing (AM). This project expects to generate new knowledge of grain refinement and phase transformations in dynamic temperature field of metal AM process and to solve the common weakness – strong mechanical anisotropy and poor fatigue life – of AM Ti components. The expected outcomes include a whole set of processing maps of AM (Ti-Cu)-based alloys tailored to demanding applications. This should provide significant benefits to aerospace, marine and biomedical industries by delivering better durability, sustainability, and cost-effectiveness.
