Hot Forming, Heat Treating, and Mechanical Evaluation of 4-Inch-Thick Ti-6Al-4V, ELI Plate
Abstract
Elevated temperature tensile properties of the Ti-6Al-4V, ELI grade alloy were determined and a forming temperature range was selected. A 7-foot-diameter hemisphere was hot-press formed from a 4-inch-thick plate according to laboratory-developed parameters. Mechanical property tests were conducted on the plate material before and after hot forming and after heat treating of the formed material. Results of these tests showed a lower tensile yield strength after hot forming and restoration of this property after heat treatment. The results indicate that a tensile yield strength of 120,000 pounds per square inch can be obtained throughout the thickness of the formed hemisphere after appropriate heat treatment.
