Locally produced Al–Zn–Mg alloy was subjected to severe plastic deformation through Equal Channel Angular Pressing (ECAP) technique at temperatures of 150 °C and 200 °C. Rectangular thick-walled medium carbon steel die (?c = 450Mpa, ?y 176Mpa) with an L-shaped channel uniform configuration provide the pressing chamber used. Four ECAP passes were imposed consecutively on set samples for temperat...

Abstract The exact calculations of the stress and strain distributions based on controlling equations for a forming process with large deformation are often difficult. To circumvent such difficulties, some analytical methods upper-bound analysis slip-line field theory have been established by making number simplifying assumptions regarding material properties modes. In this work an model was su...
