Thermal Properties and Diffusion

This lecture covers the fundamental concepts of thermal properties and diffusion in materials, discussing topics such as thermal expansion coefficient, thermal stress, atomic diffusion, ductility, toughness, endurance limit, linear thermal expansion, specific heat capacity, thermal diffusion, and temperature dependence of material properties. The instructor explains how temperature affects the dimensions and mechanical properties of materials, emphasizing the importance of understanding these phenomena to prevent serious problems and accidents.
