Equal channel angular pressing (ECAP) is one of the popular severe plastic deformation processes used to produce bulk nano structured materials. It is well known that large deformation results in microstructures with small grains and extensive dislocation cells development, often leading to corresponding increases in strength. In order to design an equal channel angular pressing (ECAP) die that can be used to process a variety of materials, it is crucial to understand the effect of die design and material parameters on the deformation behaviour, strain distribution and load requirement. In this analysis, the effect of internal die angle (Φ) and number of passes (N) on the strain behaviour of engineering materials and alloys, during ECAP was investigated by using three dimensional finite element analyses. The benefits of ECAE come from its ability to impose intense simple shear deformation through innovative die design. Unlike conventional extrusion processes, the cross section of billets extruded via ECAE is not reduced. Entire work will be carried out with the help of SOLID WORKS, ANSYS. These ultra-fine grained materials can be used in the manufacturing of semi-finished products used in the power, aerospace, medical and automotive industries.
