Additive manufacturing of metal components is an emerging technology that will transform Canada's manufacturing landscape. Integral to Canada's success in this area is the development of new materials that are tailored to the complex physical processes occurring during AM. This project will demonstrate the potential of a low-cost beta titanium alloy that is ideally suited for the rapid solidification conditions present during AM. The enhanced strength achieved through beta-Ti alloys combined with the cost savings realized through the use of pre-mixed elemental powders/powder metallurgy has the potential to disrupt component design in the aerospace industry within the next 10 years. The proposed research is divided into two areas of study. The first is the development of a structure-process-properties relationship for the alloy of interest produced through wire-arc-additive manufacturing and then heat treating. The second is the corresponding modelling of structure evolution and mechanical property evolution during processing. The joint goal of the proposed research program is to identify the optimal processing conditions for producing beta-titanium alloys via additive manufacturing. Two PhD students will be trained through this university-industry collaborative research project.

金属部件的增材制造是一项新兴技术，将改变加拿大的制造业格局。加拿大在这一领域取得成功的关键是开发针对增材制造过程中发生的复杂物理过程量身定制的新材料。该项目将展示低成本β钛合金的潜力，它非常适合AM过程中的快速凝固条件。通过β - ti合金获得的增强强度，加上使用预混合元素粉末/粉末冶金实现的成本节约，有可能在未来10年内颠覆航空航天工业的部件设计。
