Abstract

In this article, a detailed description of the friction correction, adiabatic correction, and the correction from the stroke-rate controlling process into the strain-rate controlling process on the IHS38MSV hypoeutectoid steel is provided. By using compensated data, processing maps were plotted and used to predict the optimum hot forging process. The compressive tests were performed at stroke rates ranging from 0.12 to 120 mm/s and temperatures ranging from 800 °C to 1200 °C by using ThermecMaster-Z equipment. The results showed that the correction by instant friction coefficient, which was carried out on the basis of previous research, could be extended to wider experimental conditions. The corrected data from both stroke-rate controlling and strain-rate controlling processes were in good agreement with each other, indicating that the present correction from the stroke rate into the strain-rate correction is practical and appropriate.
