Continuous extrusion of metals using Conform™ machine is a well-known process which has been used in industry for several decades as a technique for extrusion of soft metals (Al, Cu) and their alloys. New developments in continuous extrusion of metals include its use for high-strength materials and a utilization of its beneficial side effect, which is the microstructure refinement. This work describes DEFORM-3D FEM model and experimental continuous processing of titanium rods. The model traces temperature and strain fields which are then compared to experimental data obtained from continuous extrusion of titanium. The temperature of the wheel, the temperature of the input titanium feedstock and the circumferential speed of the wheel have substantial impact on the entire forming process.
