In recent years, research on ultra-fine grain materials has gained attention. While attempts have been made to improve the properties of material, it also become increasingly important decrease costs. Studies improving material revealed new production methods or required revision existing methods. this direction, severe plastic deformation come fore as a good alternative, and by with variations...
Applications of a metallic material highly depend on its mechanical properties, which greatly the material’s grain sizes. Reducing sizes by severe plastic deformation is one efficient approaches to enhance properties material. In this paper, equal channel angular pressing (ECAP) will be reviewed illustrate effects refinement some common materials such as titanium alloys, aluminum and magnesium ...
In this article, commercially pure copper samples were severely deformed by equal channel angular pressing (ECAP) up to eight passes at room temperature. The effects of severe plastic deformation on the microstructure, mechanical properties, and electrical conductivity of the copper were investigated. The microstructure evolution was followed by optical microscope and field emission scanning el...
Plastic deformation of 7075 Aluminum Alloy using Integrated Extrusion-Equal Channel Angular Pressing
Grain refinement improves the mechanical properties and formability of metals and alloys. So far, several different grain refinement methods have been proposed and studied. Severe plastic deformation is one of the most promising and efficient methods. Therefore, in the present study the possibility of imposing a two-step severe plastic deformation (Extrusion and Equal channel angular pressing) ...
