Metal Alloys: Structure and Properties

This lecture covers the structure of metal alloys, which consist of a solvent and additional solute elements, forming composites with a ductile matrix reinforced by hard precipitates. It explains the coordination of atoms, stacking arrangements, and the compactness of different structures like face-centered cubic and hexagonal compact. The lecture also discusses the number of atoms per conventional cell, interstitial sites, and phases at different temperatures. Additionally, it introduces the structure of ceramics, their ionic bond, and the tendency to form amorphous structures. The presentation concludes with the observation of atom arrangements in nanocrystals and the use of high-resolution transmission electron microscopy.
