The present study develops a logical and novel approach to understand the formation and dissolution of δ-ferrite during high temperature forging processing of 15-5 PH, Jethete (154-M), and 304 L stainless steels. This new process proposes alternative routes to examine the dissolution kinetics behavior of δ-ferrite, creating an in-depth comprehension about the synergistic effect of chemical composition, reheating temperature, deformation temperature, amount of deformation (ɛ), and strain rate (έ). In addition, well-known conventional annealing heat treatments, based exclusively on time and temperature, acted as a parameter to be further compared with the new proposed technique. The introduction of deformation at high temperatures is expected to increase the kinetics of dissolution of δ-ferrite, consequently decreasing the total heat treatment time to fully dissolve this microconstituent. Combining time, temperature, and deformation, a forging process could be represented, while the effect of those forging strategies on the formation and dissolution behavior of δ-ferrite could be understood. As the dissolution starts to take place, chemical variations along the matrix and δ-ferrite could be noticed, mainly in terms of Chromium. Aiming the homogenization of the microstructure, the Cr content tends to be equalized, not showing discrepancies between the matrix and the δ-ferrite areas.
