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...
