Physical Metallurgy is the branch of materials science that focuses on the physical properties and behaviors of metals and their alloys. It examines how the structure of metals at the atomic level influences their mechanical properties, such as strength, ductility, and hardness. This field combines principles from physics and chemistry to understand how different processing techniques affect metal performance. Researchers in Physical Metallurgy study various factors, including temperature, composition, and processing methods, to develop new materials and improve existing ones. This knowledge is crucial for industries like aerospace, automotive, and construction, where the performance and reliability of metal components are essential for safety and efficiency.
