Metallography is the study of the physical and structural properties of metals and their alloys. It involves examining the microstructure of materials using techniques such as optical microscopy and electron microscopy. By analyzing these structures, metallographers can understand how different processes affect the properties of metals, such as strength, ductility, and corrosion resistance. The field of metallography plays a crucial role in materials science and engineering. It helps in quality control, failure analysis, and the development of new materials. Understanding the microstructure allows engineers to tailor materials for specific applications, ensuring they meet performance requirements in industries like aerospace, automotive, and construction.
