Finite element analysis of surface hardening of tungsten wire by drawing process

In this paper, the finite element model was established for a multi-pass drawing of tungsten wire, and the process of tungsten wire multi-pass drawing is simulated and analyzed. The study focused on the influence of die parameters and multi-pass drawing parameters on the surface hardening of tungsten wire. Through an analysis of the impact of drawing process parameters on the surface hardening of tungsten wire, the theoretical basis for optimizing the drawing process and improving the surface quality of tungsten wire were discussed.
