摘要
Titanium alloys are advanced lightweight materials, indispensable for many critical applications(1,2). The mainstay of the titanium industry is the alpha-beta titanium alloys, which are formulated through alloying additions that stabilize the alpha and beta phases(3-5). Our work focuses on harnessing two of the most powerful stabilizing elements and strengtheners for alpha-beta titanium alloys, oxygen and iron(1-5), which are readily abundant. However, the embrittling effect of oxygen(6,7), described colloquially as 'the kryptonite to titanium'(8), and the microsegregation of iron(9) have hindered their combination for the development of strong and ductile alpha-beta titanium-oxygen-iron alloys. Here we integrate alloy design with additive manufacturing (AM) process design to demonstrate a series of titanium-oxygen-iron compositions that exhibit outstanding tensile properties. We explain the atomic-scale origins of these properties using various characterization techniques. The abundance of oxygen and iron and the process simplicity for net-shape or near-net-shape manufacturing by AM make these alpha-beta titanium-oxygen-iron alloys attractive for a diverse range of applications. Furthermore, they offer promise for industrial-scale use of off-grade sponge titanium or sponge titanium-oxygen-iron(10,11), an industrial waste product at present. The economic and environmental potential to reduce the carbon footprint of the energy-intensive sponge titanium production(12) is substantial.
