Effect of Die Profile on Mechanical Properties of Product in Extrusion of Rods

In any metal forming process, both the strain rate and deformation rate depend on the die profile. The die profile also, is responsible for the non-uniformity of the deformation along the cross-section. These affect the quality and mechanical properties of the product. Therefore, if a die is designed, in which the affecting variables can be controlled spontaneously it is hoped to obtain a product with a desired quality. In this paper, the effect of the die profile on the mechanical and metallurgical properties of the product is investigated.
