This project aims to pioneer an unprecedented class of ultrahigh-strength titanium alloys for 3D printing by capitalising on both the alloy design theory of ultrahigh-strength steels and the unique capability of laser-based 3D printing. The planned research expects to significantly advance the knowledge base of advanced metallic materials and metal 3D printing via atomistic level characterisation and systematic mechanical property evaluation in relation to specifically tailored 3D printing conditions. Expected outcomes include a group of ultrahigh-strength novel titanium alloys for 3D printing and a new alloy design theory. This should provide significant benefits to the manufacturing industry to support the national economy and security.

该项目旨在通过利用超高强度钢的合金设计理论和基于激光的3D打印的独特能力来利用一类前所未有的超高强度钛合金，用于3D打印。计划的研究预计，通过原子能水平表征和系统的机械性能评估，与专门量身定制的3D打印条件有关，将显着提高高级金属材料和金属3D打印的知识库。预期的结果包括一组用于3D打印的超强度小说钛合金和一种新的合金设计理论。这应该为制造业提供巨大的好处，以支持国民经济和安全。
