The present paper is the second part of a previously published overview entitled “ten years of severe plastic deformation (SPD) in Iran”. Part I concentrates on the equal channel angular pressing (ECAP). In this part, the focus is on the accumulative roll bonding (ARB) because, currently, Iran is ranked the first in the world by the total number of publications in this field. In the present sec...

In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. However, the improvement of low cycle fati...

The full annealing AA6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ECAP) and cold rolling (CR) in order torefine its microstructure and to improve its mechanical properties. According to the results of hotand cold tensile tests, the combination of ECAP and CR significantly affected the final strengthand ductility of studied...

The evolution of microstructure and mechanical properties of a magnesium cast alloy (AZ31) processed by equal channel angular pressing (ECAP) at two different temperatures were investigated. The as-cast alloy with an average grain size of 360  was significantly refined to about 5  after four ECAP passes at 543 K. Grain refinement was achieved through dynamic recrystallization (DRX) du...

The main limitation of the Equal Channel Angular Pressing (ECAP) is very high required punching force for pushing metallic sample to next channel. Frictional forces in ECAP process are responsible force. participation exit and entrance channels total friction has not been studied experimentally hitherto. Through current study, two dies (1) with (normal die) (2) only one channel (the was missed)...

This paper presents a finite element simulation of equal channel angular pressing (ECAP) since it is one the most common and successful severe plastic deformation techniques. study reports influence significant factors influencing ECAP technique. Through simulation, effect die geometry, workpiece speed on effective strain distributions, damage, loads, were investigated. The method different mat...

The technique known as Equal Channel Angular Pressing (ECAP) has gained prominence a transformational method for improving the mechanical characteristics of metals and alloys by subjecting them to intense plastic deformation. This study explores significant difficulties that arise when using on Aluminium 2024-Beryl Metal Matrix Composites (2024-BMMCs), providing detailed analysis complex intera...
