The objective of this program was to develop an economical sheet titanium alloy. The approach was to build on the earlier work with emphasis on mill product economics consistent with formability, fabricability, and other properties required by the ultimate user. Including alloys from the earlier contracts, more than 60 compositions were evaluated. These were narrowed to three final compositions, Ti-8V-7Cr-3Al-4Sn-1Zr, Ti-8V-4Cr-2Mo-2Fe-3Al, and Ti-15V-3Cr-3Al-3Sn. Further work is recommended on all three. Each alloy exhibits good strip producibility potential while meeting the airframe industries stated cold minimum bend requirements. Each alloy showed Erichsen cup draw depths exceeding 0.35 in. after simulated strip processing to about .040 in. gage. Author
