The effect of strain-hardening features of porous materials treated by cold extrusion through a conical die is studied theoretically in the present paper. The theoretical model developed by using the fundamentals of the Plasticity Theory of Real Porous Materials investigates all technological parameters affected in the case of extruding bimetallic tubes with a porous internal layer. Comparative analysis between strain-hardened and ideally plastic materials used in the fabrication of bimetallic tubular components, as far as their effect on various technological extrusion parameters is concerned, such as variation of porosity, applied load, level of total deformation, etc., has been conducted successfully, providing, in this manner, with useful concluding remarks from engineering point of view.
