Production of lightweight metals with a higher strength to weight ratio is always the main goal of researchers. In this article, equal channel multi angular pressing (ECMAP) process as one of the most appealing severe plastic deformation (SPD) methods on production of ultra-fine grained (UFG) materials studied. Two main routes A and C investigated by FEM and compared with each other from differ...

Abstract. Equal channel angular pressing (ECAP) as a severe plastic deformation (SPD) technique was employed for consolidation of AZ31 magnesium chips. The chips were consolidated at temperature 300 °C following ECAP route A up to two passes. optical and scanning electron micrographs reveal that have taken place the quality improves with number passes hence total imposed strain. Vickers hardnes...

Equal Channel Angular Pressing (ECAP) is currently being widely investigated because of its potential to produce ultrafine grained microstructures in metals and alloys. A sound knowledge of the plastic deformation and strain distribution is necessary for understanding the relationships between strain inhomogeneity and die geometry. Considerable research has been reported on finite element analy...
