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.

该项目旨在重塑具有超高拉伸强度和明显高周期疲劳强度的β-钛合金（β-TI）合金的设计和制造。它将利用三维打印，以使铁（Fe）和铬（CR）充分利用作为beta-stabilizers的Ti，而无需隔离导致β-罚款缺陷。预计该项目的结果从根本上改变了超高强度β-TI合金的设计和制造，并显着扩展了金属三维印刷的能力，并促进了金属三维印刷的知识库和ti合金。它们进一步为在广阔的金属领域中制造其他类似工程合金提供了一种战略解决方案。
