Abstract:

The objective of the program was to develop a metastable beta titanium sheet alloy which could be formed by standard sheet metal shop equipment and then reliably heat treated to a high strength level. It is anticipated that such an alloy will reduce initial manufacturing costs by eliminating costly hot-forming operations and by allowing greater field repair capability. Such an alloy composition was developed. It, however, did not exhibit the desired high cold formability and was not heat treatable to a high strength level with usable ductility and toughness. An alloy of a composition that resulted in cold deformation by slip exhibited a better balance of cold formability and mechanical properties after heat treatment. The alloy was Ti-3Al-15V-3Cr-3Sn. A secondary objective was the study of compositional effects as related to solutionizing cycle, cooling rate, deformation mode and heat treat response. Nineteen alloy compositions were investigated.
