DEFORMATION PROCESSING OF ANISOTROPIC METALS.
Abstract
This work involves more systematic experiments on superplasticity in the 5 Al-2.5 Sn titanium alloy. Tensile tests have been made from room temperature to 1065C, which is slightly above the reported alpha-beta transition temperature. Tensile yield strength and elongation for an initial strain rate of 0.025/minute are shown as a function of temperature. A measure of strain-rate sensitivity of the flow stress is given. The temperature dependence of m is given for two different ranges of pulling speed. The data indicate that m increases with temperature in 2 stages, a sharp rise at about 600C to values of 0.3 - 0.4 followed by another increase to about 0.5 on approaching alpha-beta transformation.
