Materials: from Chemistry to Properties

This lecture covers the transition from chemistry to properties of materials, focusing on mechanical engineering. Topics include atomic structure, periodic table, stoichiometry, chemical bonds, material structure, mechanical properties like elasticity, plasticity, ductility, hardness, toughness, fatigue, and wear. It also discusses thermodynamics, equilibrium, phase diagrams, thermal properties, diffusion, electrical and magnetic properties, chemical reactions, batteries, electrolysis, and corrosion. The lecture emphasizes the importance of understanding material composition, microstructure, and fabrication processes to predict mechanical, thermal, electrical, and magnetic properties, as well as environmental effects like corrosion and wear. It also explores the selection, design, and assembly of materials for specific performance requirements, such as in the development of modern skis.
