Dual Twist Channel Angular Extrusion (DTCAE), a modified advanced Severe Plastic Deformation (SPD) technique, is investigated through Finite Element Analysis (FEA). The proposed technique is the cumulation of multiple deformations with Equal Channel Angular Pressing (ECAP) to enhance the process efficiency and strain induction. The DTCAE die facilitates a twist of 90°, before the 110° ECAP, a 45° twist after ECAP in the reverse direction, followed by the extrusion. The extrusion at the die exit
