Metal Matrix Composites (MMCs) are materials made by combining a metal with other materials, such as ceramics or fibers. This combination enhances the properties of the metal, making it stronger, lighter, and more resistant to wear and corrosion. MMCs are commonly used in industries like aerospace, automotive, and sports equipment due to their improved performance characteristics. The process of creating MMCs often involves techniques like casting, powder metallurgy, or mechanical alloying. By carefully selecting the metal matrix and reinforcement materials, engineers can tailor the composite's properties to meet specific requirements, leading to innovative applications in technology and manufacturing.
