The present work undertakes an experimental investigation into the influence that process parameters, namely forging temperature, percentage deformation, and cooling rate in conjunction with their interactions on the microstructure and mechanical properties of vanadium micro-alloyed steel (38MnSiVS5) undergoing hot forging operation. The variations observed in the mechanical properties are explained in terms of the microstructure obtained. A full factorial-based design has been made use of to account for all possible combinations of factors in order to obtain a thorough study. Empirical models that relate the response and process parameters have been developed from the results that have been obtained from these experiments. These models are validated by making use of analysis of variance (ANOVA). Response surface plots for each response are analyzed, and the optimal parameter setting for each response is determined. The study discovered an outsized variation in the microstructural features corresponding to the various thermomechanical conditions under examination. In order to optimize all the responses at the same time, desirability function is adopted.
