Formable Sheet Titanium Alloys.
Abstract
The objectives of this program were to evaluate three promising experimental alloys by optimizing mill processing using formability, formageability, and uniformity and consistency of properties as the criteria. The three alloys (1) Ti-8V-7Cr-3Al-4Sn-1Zr, (2) Ti-8V-4Cr-2Mo-2Fe-3Al, and (3) Ti-15V-3Cr-3Al-3 3Sn were selected. The three mill processes examined were: (1) Conventional cold strip processing (2) Conventional hot mill processing to plate followed by cold hand mill rolling to sheet (3) Conventional hot mill processing. The materials from the two cold roll processes showed the better forming potential and were selected for extensive mechanical property and formability evaluation. All three alloys offer improved mechanical properties over those for existing titanium sheet alloy airframe materials. Further work is recommended for one or more of these alloys because of the combination of economy in formed parts and mechanical properties.
