Abstract: Through the optimization of tool parameters and the wedge shape, titanium alloy workpieces with excellent surface and internal qualities were formed by flat cross wedge rolling (CWR) adopting tools without surface grooves. Firstly, the thermomechanical coupled model of CWR for TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) titanium alloy was established in the finite element (FE) software DEFORM-3D, and the effects of forming angle α, stretching angle β and section reduction Ψ were studied. The results showed that in the c… Show more
