Heavy deformations like cold rolling or drawing, can result in significant refinement of the microstructure at low temperatures. Formation of such nanostructures could be achieved by severe plastic deformation methods providing very large deformations at relatively low temperatures under the high pressures imposed. A one common example of these methods is equal channel angular pressing. The aim of the study is to design and build a computer model for simulation of the formation of nanostructured bulk materials by severe plastic deformation methods achieved by equal channel angular pressing. To achieve the aim, finite element method will be used. The model constructed will also consider the severe plastic deformation process parameters like loading type and condition, die geometry and angle, die friction factors, strain rates, material properties, and their effect on the process efficiency. The microstructural changes will also be studied.
