Lecture
This lecture by the instructor covers the various defects found in crystals, including point defects like interstitial atoms and vacancies, dislocations, grain boundaries, and the impact of grain boundary networks on material behavior. The presentation also delves into topics such as misfit dislocations, the glass transition, amorphous materials, quasicrystals, fractals, and void formation due to electron irradiation in nanotwinned copper.
