The thermodynamics of metallurgy involves the study of energy and heat interactions during metallurgical processes, crucial for understanding phase transformations, reaction equilibria, and the efficiency of metal extraction and refining. It applies principles such as Gibbs free energy and entropy to predict the feasibility and direction of chemical reactions in metal production.

Metallurgical processes encompass the extraction, refining, and alloying of metals from ores, employing both physical and chemical methods to enhance material properties for industrial applications. These processes are crucial in transforming raw materials into usable metal products, impacting sectors like construction, automotive, and electronics.

Phase transformations involve the change of a material from one state of matter to another, driven by variations in temperature, pressure, or composition. These transformations are pivotal in materials science as they influence the mechanical, thermal, and electrical properties of materials, impacting their applications and performance.

Gibbs free energy is a thermodynamic potential that measures the maximum reversible work obtainable from a system at constant temperature and pressure. It is a crucial criterion for determining the spontaneity of a process, where a negative change in Gibbs free energy indicates a spontaneous reaction.

Gibbs free energy

Entropy is a measure of disorder or randomness in a system, reflecting the number of microscopic configurations that correspond to a thermodynamic system's macroscopic state. It plays a crucial role in the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time, driving the direction of spontaneous processes and energy dispersal.
