In order to accelerate the application of Ti-B25 titanium alloy in ship communication system,DEFORM-3 D finite element software was used to simulate the pipe extrusion process under the deformation temperature of 900 ℃ and the strain rate of 0. 1 s-1 with the constructed constitutive equation and the optimized process parameters in the previous work. And the pipe extrusion experiment of Ti-B25 alloy was performed to validate the results of FE simulation. The results show that the pipe blank of 62 mm × 12 mm can be successfully extruded under the deformation temperature of900 ℃ and the strain rate of 0. 1 s-1. The pipe blank has good surface quality and recrystallized microstructure. After solution aging treatment at 830 ℃/1 h + 600 ℃/8 h,the pipe blank exhibits good stress-plastic matching,which meets the requirement of the pipes used in the shipboard antenna.
