Abstract
This paper aims to study bulk severe plastic deformation processes capable to produce ultrafine grain and also nanostructured 3D materials, interesting for processing in current industry. Samples of copper alloy were solution treated and then were subjected to repetitive Equal Channel Angular Pressing at room temperature in 1 to 8 passes, using route C. Severely deformed specimens were studied after each deformation pass. Their microstructural evolution and mechanical properties were investigated. Optical microscopy progression is evaluated on each separate ECAP pass. It is well known that although copper is a deficient resource it is used to the same extent as aluminum, a rich resource on the earth’s crust. This research signs up in the category of new technologies for obtaining bulk metallic nanostructures that allow more judicious use of copper alloys by the substantial improvement of properties of use.
