Abstract
In the present study, copper tubes were subjected to severe plastic deformation through integrated extrusion-equal channel angular pressing (Ex-ECAP). Plastic deformation characteristics were analyzed using finite element simulation and resultant microstructures were characterized by optical microscopy. Also, X-ray diffraction patterns were utilized to calculate crystallite size. Results showed that integrated Ex-ECAP could be successfully applied on metallic tubes. Meanwhile, the resultant sub-grain size was measured to be in the range of 360–550 nm by Williamson–Hall method. Optical micrographs taken from the cross section of deformed sample demonstrated that initial grains in the plane perpendicular to flow direction remained equiaxed after deformation by Ex-ECAP and their sizes were decreased from 16 to 4 μm after deformation.
