Oxygen is the bottleneck issue of titanium powder metallurgy, which radically deteriorates the ductility of titanium. This project aims to develop the essential fundamental knowledge and technical solutions to mitigate the detrimental effect of oxygen on the ductility of as-sintered titanium products and enable the net-shape fabrication of low-cost high-performance titanium alloys. This will be achieved by utilising the inexpensive and unique titanium hydride powder, rather than titanium metal powder, and by developing effective oxygen scavengers. The outcomes will form a robust basis for the creation of a viable titanium hydride powder metallurgy business.

氧是钛粉末冶金的瓶颈问题，它从根本上恶化了钛的塑性。该项目旨在开发必要的基础知识和技术解决方案，以减轻氧对烧结钛产品延展性的不利影响，并实现低成本高性能钛合金的净成形制造。这将通过利用廉价和独特的氢化钛粉末而不是钛金属粉末，并通过开发有效的氧清除剂来实现。这些成果将为建立可行的氢化钛粉末冶金业务奠定坚实的基础。
