In this research, samples of AlMg0.7Si aluminum alloy are deformed up to three passes using equal channel angular pressing (ECAP). Formation of a sub-micron structure after three passes of ECAP is demonstrated. Microstructural stability of the samples is investigated at temperatures of 300-500 °C. At 300 °C, fine recrystallized structure forms after 10 min which remains stable when the ...

Effects of annealing treatment after equal channel angular pressing (ECAP) on the interface properties and shear bond strength of Al/Cu bimetallic rods were investigated. For the as-deformed samples, the one with two passes of ECAP indicated higher shear bond strength. Formation of a layer of intermetallic compounds after annealing treatment is confirmed. In general, by increasing annealing tem...

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...
