Abstract

Abstract During the forming of metals, the contact resistance between the workpiece and the die can have an important influence upon the temperature distribution in the material being formed and on the quality of the end product. In order to predict the contact resistance, a technique is being developed which will enable accurate determination of the contact resistance. This technique involves direct temperature measurement at the die/billet interface during deformation and subsequent use of inverse heat transfer model to calculate the contact resistance. The preliminary results indicate that the method can provide a reliable means of predicting the contact resistance.
