Intermetallic compounds are a class of materials consisting of two or more metallic elements in specific stoichiometric ratios. These compounds have unique properties and characteristics compared to traditional metals, such as high melting points, high hardness, and often exhibit superior mechanical, electrical, and magnetic properties. Intermetallic compounds are being researched for various applications, including in aerospace, automotive, electronics, and catalysis. The study of intermetallic compounds involves understanding their crystal structures, phase transitions, and thermodynamic properties to optimize their properties for specific applications.
