| Abstract Scope |
As aerospace and defense applications become increasingly demanding, the need for lightweight, strong, and temperature capable materials has become even more relevant. Modern jet engines rely on titanium alloys that exhibit relatively high elevated temperature strength, and emerging markets such as hypersonics have even more challenging requirements. ATI has undergone a focused effort to improve upon legacy titanium alloys to meet these needs, iterating off high-temperature capable alloys such as Ti-6Al-2Sn-4Zr-2Mo, Ti-5Al-2Sn-2Zr-4Mo-4Cr, and Ti-4Al-4Mo-2Sn. Specifically, a new beta-rich alloy, ATI Titan 171™ has been found to have superior performance at temperatures up to 1000°F.
This presentation will focus on the research and development of ATI Titan 171™, from lab scale trials to mill scale billet heats, including forging, rolling and powder developments, and an overview of material properties and microstructure, as ATI strives to usher in the next generation of titanium alloy performance. |
