Introduction to Materials Science

This lecture covers the basics of materials science, including material structure, crystal structures, metal alloys, defects in crystals, and the structure of ceramics. It explains concepts such as atomic radius, coordination number, and interstitial sites, as well as the properties of materials like mechanical resistance, elastic limit, and toughness. The lecture also touches on the structure of ceramics, their ionic bonds, and their applications in high-tech fields like superconductors and ferroelectrics.
