Analysis of Deformation Forces in Simulation of a New Thermomechanical Wire Processing

This work is concerned with the study of the emerging deformation forces during the implementation of a new method of thermomechanical wire processing that is a combined process including successive stages of wire drawing and cooling in a special chamber with liquid nitrogen.The analysis of forces is carried out by finite-elements' modelling of the combined process within the DEFORM program.As found, the presence of intermediate heating to ambient temperature allows calculating the force according to the Krasilshchikov formula and the well-known nomogram of the tensile strength of AISI-316 steel at 20C with minimal errors.The deformation without intermediate heating leads to the negative temperatures in the workpiece section in the second and third drawing cycles.
