Development of Processing Maps for Hot Deformation: Algorithm and Common Errors

The development of processing maps using the dynamic materials modeling (DMM) approach is a widely used method for choosing the appropriate process parameters for the thermomechanical processing of any material. This paper highlights the correct algorithm for developing the processing map by calculating the metallurgical power dissipation efficiency (η) and the newly proposed binary instability parameter (β). Further, common errors that can arise during the computations, and their consequences are also highlighted.
