Abstract

A hybrid algorithm based on the finite element method, Monte Carlo model, and Hall–Petch relationship is utilized to predict the mechanical properties of the rods after cold forging at different degrees of deformations and heat treatments at different temperatures and times. The results show that the flow stress and hardness of the rods after forging and those of the forged rods after the heat treatments are decreased from their center to surface. However, with increasing the temperature and time of the heat treatment the flow stress and hardness are decreased, their effects are not considerable. In addition, the distribution of the mechanical properties of the forged rods after the heat treatments is more uniform than the one before the heat treatments. Moreover, to verify the predicted results the hardness values of the rods after forging and heat treatment are measured experimentally and compared with the predicted ones.
