Title: Finite element simulation and experiment of isothermal die forging process of TC18 Ti alloy disc
Abstract: Arrhenius constitutive relationship of TC18 Ti alloy obtained from thermal simulation test was used to simulate the isothermal die forging of reduced-scale TC18 disc by finite element method. The suitable deformation conditions were obtained and applied to guide the experiment through systemically investigating the influence of deformation temperature,rate and friction factor on the isothermal die forging process. The result show that the suitable isothermal die forging conditions are that the temperature is 840 ℃,rate is 0.1 mm/s and friction factor is 0.03. The TC18 Ti disc is successfully fabricated under the guidance of finite element simulation,while the accuracy of simulation is also verified by the forging experiment. The related investigation can provide the numerical and technological support for other complex components.
