Abstract

Abstract : Combining of rotary extrusion and equal channel angular pressing (ECAP) leads to the ECAP‐Conform process, which is one of the few successful continuous severe plastic deformation processes. Sample before reaching the ECAP die is influenced by three main deformations of rolling, bending, and forging, which can affect the microstructure and mechanical properties of the material. The effects of these steps on the microstructure and properties of AA1100 alloy are studied based on the simulation and experimental investigations. It is found that these steps significantly affect the material and they should be considered for evaluation of properties compared with the conventional ECAP. Abstract : During ECAP‐Conform process, three main deformations steps of rolling, bending and forging affect the properties of sample before reaching the ECAP die. The influences of these steps on the properties of 5 mm annealed Al bar are discussed based on the simulation and experimental results. Yield and ultimate strengths change from 80 and 100 MPa to 110 and 120 MPa, respectively, during mentioned steps.
