This project aims to reshape the design and fabrication of beta-titanium (beta-Ti) alloys that offer ultrahigh tensile strength and significant high cycle fatigue strength. It will exploit three-dimensional printing to enable the full use of Iron (Fe) and Chromium (Cr) as beta-stabilizers for Ti without segregation leading to beta-fleck defects. The outcomes of this project are expected to fundamentally change the design and fabrication of ultrahigh-strength beta-Ti alloys and to significantly extend the capabilities of metal three-dimensional printing, as well as advancing the knowledge base of both metal three-dimensional printing and Ti alloys. They further provide a strategic solution to the manufacture of other similar engineering alloys in the broad field of metals.

该项目旨在重塑提供超高拉伸强度和显著高周疲劳强度的β-钛(β-Ti)合金的设计和制造。它将利用三维打印技术，充分利用铁(Fe)和铬(Cr)作为钛的β稳定剂，而不会出现导致β斑点缺陷的偏析。该项目的成果有望从根本上改变超高强度贝塔钛合金的设计和制造，显著扩展金属三维打印的能力，并推进金属三维打印和钛合金的知识库。它们还为在广泛的金属领域制造其他类似的工程合金提供了战略解决方案。
