摘    要:钛合金具有比强度高、中温性能好、耐腐蚀、无磁、焊接性能好等特点,是一种重要的金属材料。采用Minitab软件中的响应面设计建立TC4钛合金在超塑性高温拉伸的网络模型,利用该模型可获得该合金的最佳伸长率、变形条件和各影响因素间的显著性效果,为超塑成形的热加工工艺和质量控制提供理论依据。

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.
