Abstract:Titanium alloy has high intensity, good medium temperature performance, corrosion resistance, no magnetic, good welding performance characteristic, and it is a kind of important the metal materials. Based on the Minitab software of response surface, the superplastic high temperature tensile network model of TC4 titanium alloy was establistled and the model was used for the alloy to obtain optimal elongation, deformation condition and the factors of significant effect. This can provide a theoretical basis for the superplastic forming of thermal processing and quality control.
