Metals: from Atom to Solid

This lecture covers the transition from individual atoms to solid metal structures, exploring concepts such as crystal lattices, compactness, and different cubic systems like face-centered cubic and hexagonal close-packed. It also delves into the patterns and structures of metals and alloys, including examples like diamond carbon and intermetallic phases. The instructor discusses the allotropic forms of pure iron, solid solutions, and the accommodation of foreign atoms in crystal lattices, highlighting the isotropic properties and modularity of metals.
