Description
Summary:Equal Channel Angular Extrusion (ECAE) is known as a severe plastic deformation process and material is deformed without any geometrical change. It is widely used for obtaining high mechanical properties from the product. Direct Extrusion is another plastic deformation process in which a workpiece is reduced in cross-section by forcing it through the die opening of a small cross-sectional area than that of the original billet. In this study, these two processes are combined together via using DEFORM 3D which is a very specialized software for metal forming operations. Lead is used as workpiece material to simulate hot forming conditions and also process parameters (die angle and die land length) were investigated. The forming load and strain components were calculated from the FEM results obtained from DEFORM 3D software.
