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...

In recent years, the fabrication of bulk materials with ultra fine grain sized materials processed by SPD methods. Different techniques have been used to introduce large plastic strains in to bulk metals such as Equal Channel Angular Pressing (ECAP) [1-3], Accumulative Roll Bonding (ARB) [4-7], Repetitive Corrugation and Straitening (RCS) [8,9], Constrained Groove Pressing (CGP) [5] and Constra...

Multilayer composites have recently attracted considerable attention due to their ability take advantage of the benefits various metallic materials simultaneously. The present study is first use parallel tubular channel angular pressing (PTCAP) as a severe plastic deformation method fabricate bimetal Al/Mg tube. This process was applied on commercially pure aluminum along with an AM60 magnesium...
