| Description | This work aims to investigate the temperature rise in Aluminum alloy 6061 due to deformation heating in equal channel angular pressing (ECAP) and high-pressure torsion (HPT) processes using finite element method. The roles of various parameters are investigated and the heating of ECAP die due to billet deformation is included in the simulations. The results show that while the work-piece moves in the exit channel, the generated heat is transferred to die via conduction and therefore the temperature isosurfaces in die are extended in the direction of inlet and exit channels. The dependency of maximum work-piece temperature to velocity is more than its dependency to friction. Increasing the plunger velocity increases the difference between maximum and minimum temperatures. Additionally, the maximum work-piece temperature is attained at the deformation zone. The temperature rise in HPT is less than ECAP due to the small size of the HPT work-piece compared to ECAP. Not only the work-piece size, but also the good heat conduction of aluminum makes the temperature distribution roughly uniform in HPT.
