Method development for the calculation of the metal drawing passes schedule to which the hollomon curve applies

Abstract

Starting from the assumption that the hardening curve (the effective stress) during the metal cold drawing can be mathematically interpreted using a theoretical method for calculating the deformation stress state, the lower and upper bound solution, it was possible to develop a method for the calculation of the passes schedule. The theoretical analysis gave a complete insight into the process. The mathematical interpretation of the Hollomon curve was determined based on the experiments for the CuNi2Si alloy that was used for the method development and analysis.
