摘要: Abstract The study of superplastic forming in aluminium alloys has involved many efforts for its cost and engineering advantages. Mechanistically, the ability a crystalline material to undergo behaviour is usually linked submicrometer grain size. Equal channel angular extrusion (ECAE) an innovative technique developing ultrafine-grained (UFG) microstructure by introducing severe plastic deformation bulk with no changes their cross-section. This work presents using finite element modelling (FEM) ECAE process two usual angles 90° 120°, considering different friction conditions. Deformation imparted through process, studied modifying processing conditions determining effect between dies billet. Moreover, experimental processes been carried out 3103 Al–Mn alloy 5083 Al–Mg alloy, Route A. angle was 120° former latter, conducted at room temperature 200 °C, respectively.
