通过使用廉价合金元素铁、碳替代昂贵的钒元素制备了低成本超高强钛合金Ti-xFe-3Al（x=7，10，12），利用Gleeble-3500型热模拟试验机研究该合金的热变形行为，在此基础上确定了该合金的锻造工艺。结果表明：Ti-xFe-3Al合金在850℃、10 s^-1应变速率下变形时，应力-应变曲线的平台阶段较为平稳，且流变应力在400 MPa以下，符合实际锻造生产条件；Ti-xFe-3Al合金较佳的精锻温度为（850±20）℃；锻态合金中无剪切组织，且抗拉强度高于1 200 MPa。

Low-cost titanium alloys (Ti-xFe-3Al) with super high strength were prepared by using low-cost alloying elements, iron and carbon, instead of higher cost vanadium element. The alloy's thermal deformation behavior was studied by using Gleeble-3500 thermal simulation tester, and forging processes of the alloys were determined. The results show that the stress-plat in stress-strain curve was more stable when deformation temperature of the alloys was 850℃ and strain rate was 10 s^-1, and the flow stress was under 400 MPa. It was suitable for the forging process. Based on that, the better forging temperature of the alloys was (850±20)℃. Shearing band did not find in the as-forged alloys, and the alloy's tensile strength was over 1 200 MPa.
