Prediction of damage zone in hot forging die and suggesting proper heat treatment for improving die service life

Abstract

In the present research, using MSC Super Forge simulation software and analysis of stress, strain, contact pressure, and temperature distribution in different points of hot forging operation of a work piece and also by considering the interaction between the work piece and die, the zones of die which are prone to early failure and damage have been predicted. The results of simulation have been compared with experimental results of die service. Simulation outputs show a good agreement with practical conditions. In the next step, after studying the effect of heat treatment on the die performance, a proper heat treatment procedure is introduced to improve die service life. Finally, capability of this solution to overcome die damages would be verified with practical behavior of dies.
