BIAXIAL TENSILE BEHAVIOR OF TI-5AL-2.5SN ALLOY

Abstract

The elastic and plastic tensile properties of two sheets of 5Al-2.5Sn titanium alloy were determined. The effect of various annealing temperatures up to 1900 F on these properties were obtained on one sheet. Two closed-end cylindrical pressure vessels which had reduced wall thicknesses away from the longitudinal and circumferential welds were fabricated from each sheet. Two of the pressure vessels from one sheet exhibited yield improvements which were slightly lower than those predicted by the Hill-Backofen anisotropic yield criterion. The other two vessels yielded at less than that predicted by the Von Mises yield criterion. All vessels exhibited exceptionally high burst strengths as compared to the uniaxial tensile strengths.
