In order to obtain forming process scheme and suitable parameters for TC4 titanium alloy frame part,
Msc/ Superforge software was used in simulating overall hot extrusion and segment parts hot extrusion. The simulation results show that high extrusion force and difficulty in forming in overall extrusion process made it not suitable for this product,but low extrusion force in segment parts hot extrusion resulted in good shaping. This process is suitable for this product and the initial extrusion temperature 920, extrusion speed 3mm/ s is better condition for it.
