5. Conclusion In this study, a 3D finite element model based on plastic and elastic-plastic formulation is developed using  Zr-4 alloy produced with a 1.25 m/min feed rate exhibits lower residual stresses over samples produced at 2 m/min at the same die angle.  The dies with a die angle of 4 o have led to the least tensile residual stress at the center and more compressive residual stress at the surface of Zr-4 alloy. It is the best choice for carrying out an experimental test to validate the simulation results.  The residual stresses values are consistent across the axial (length) of the billet sample.  The Zr-4 alloy beyond the die angle of 10 degree (10 to 14 o ) has irregular deformation.
