In this paper, we explored the feasibility of a new continuous severe plastic deformation (SPD) technique, which combines continuous extrusion forming (Conform) and high pressure torsion extrusion (HPTE), we defined it as Conform-HPTE. A finite element method (FEM) simulation model of this process was established using QForm software. The results showed that the novel Conform-HPTE technique can owe both the advantages of Conform and HPTE, thus it could be used for industrial production of aluminum alloys due to its low energy input, no limit for billet length and large shear strain during one deformation pass. The effects of tool geometry and processing parameters on the extrusion load, temperature, strain evolution and metal flow during the Conform-HPTE process were discussed.
