The invention discloses a preparation method of titanium alloy bars. The finished titanium alloy bars are prepared through the following steps: heating prepared TC4-DT titanium alloy ingots to 1150 to 1200 DEG C; cogging and forging a beta phase zone of the ingots with a fast forging press; heating forging stocks to Tbeta-50 to Tbeta-20 DEG C through a resistance furnace; carrying out repeated upsetting and extension forging by the fast forging press; forging forged stocks to required dimensions at a forging temperature of Tbeta-70 to Tbeta-40 DEG C to obtain titanium alloy bars with uniform tissues; and carrying out duplex annealing on the obtained titanium alloy bars with the uniform tissues. The preparation method has the advantages of convenient operation, strong controllable technology, high stability of batches of prepared bars, and good repeatability. The titanium alloy bars prepared through the method of the present invention has the advantages of strong plasticity, qualified macrostructure, high strength and fracture toughness, and low fatigue crack growth rate.
