Title: Designer's guide to the mechanical properties and fracture toughness of titanium 6Al--6V--2Sn

Abstract

During the Phase 3 design of the B77 laydown bomb, titanium 6A1-6V-2Sn was chosen for certain structural components. Comprehensive mechanical property and fracture toughness information for this alloy were lacking, necessitating a test program keyed to the anticipated weapon environment and stockpile-to-target sequence. This report covers the mechanical tests of strength, notch sensitivity, and fracture toughness that were conducted. The results showed the duplex annealed condition to be most tough and least notch sensitive. It was found that any change in heat treatment, test temperature, or loading rate that boosted strength did so at the expense of fracture toughness and notch sensitivity.
