Lecture
This lecture covers the fundamental concepts of metals, from atomic structures to solid formations, including crystalline structures, metallic bonds, and the periodic table. It explores the properties, microstructures, and mechanical behaviors of metals, as well as their applications in civil engineering. The instructor emphasizes the optimization of grain sizes, heat treatments, and the control of metal microstructures to enhance properties. Additionally, the lecture discusses the importance of metals as conductors, their recyclability, ductility, and resistance. It also addresses the challenges related to corrosion, extraction processes, and the environmental impact of metal production.
