For a new type low-cost titanium alloy TC4LCA, the influences of forming temperature, holding time and bending radius on the forming accuracy, microstructure and mechanical properties of TC4LCA V-shaped parts were studied by bending experiments of V-shaped parts. The results show that with the increasing of forming temperature from 700 ℃ to 800 ℃ and holding time from 5 min to 25 min at bending radius of t, the springback angle of the bent part decreases from 16′ to 0′, and the wall thickness reduction rate increases from 2.6% to 5.8%. The Vickers hardness and strength both decrease slightly, and the performance reaches 90% of the base material. Under the condition of forming temperature of 750 ℃ and holding time of 15 min, when the bending radius decreases from 2.0t to 0.5t, the wall thickness reduction rate of the part increases from 2.3% to 6.7%, and the springback angle increases from 2′ to 9′. The research results provide a basis for rational design of hot bending process parameters for low-cost TC4LCA titanium alloy V-shaped parts, and reduce the costs while ensuring the service performance of titanium alloy parts to expand their application range.
