Physical metallurgy is the branch of metallurgy related to the theory of phase transformations in metal and alloys. It deals mainly with mechanical and magnetic/electric/thermal properties of metals – treated by the discipline of solid-state physics. This eLearning course on physical metallurgy from Tata Steel Digie-Shala will help you to develop the understanding of basic principles of physical metallurgy like heat treatment, phase transformation, phase diagrams, precipitation hardening, and aging.
