Texture simulation of forging process of TB6 liner and its comparison with copper and tantalum

Abstract:

The texture formation of TB6 titanium alloy under different forging processes was investigated by simulation, and compared with tantalum and copper. Firstly, the difference of temperature, equivalent stress and equivalent strain in different parts of TB6 titanium alloy during square drawing was analyzed by finite element method, after that, VPSC (visco-plastic self-consistent model) was used to simulate the texture evolution of different materials in forging process and make a comparative analysis. The results show that the central textures of BCC β phase in titanium alloy and Ta are not uniform with the edges, and the FCC copper textures have little fluctuation. The multi-side drawing is beneficial to weaken the {110} strong texture which is parallel to the axial direction during square drawing, and the compression texture can be retained in the drawing process.
