A new class of titanium alloys developed for additive manufacturing

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.
