Theoretical analysis of equal channel angular pressing method for grain refinement of metals and alloys

Abstract

The most innovative ECAP method is used for grain refinement of bulk crystalline material to ultrafine structure and subsequent improvement in mechanical properties of materials. In this research paper, discussion has been made about the exertion of earlier researchers related to improvement of microstructure and mechanical properties for industrial fabrication. In general, the result obtained shows that this method is useful for grain refinement up-to certain level due to high imposed shear strain. It has also been observed that strength is also increased with ductility as desired in most of the cases.
