A thermal process commonly used for ferrous materials that have been forged, cast, or hot rolled involves heating the component to its critical hardening temperature. This process transforms the coarse ferrite grains into finer austenitic grains, altering the microstructure of the material. It can be conducted in air or an inert atmosphere to avoid oxidation and decarburization.
