Learn the fundamental principles of nucleation and growth kinetics in materials science through this 23-minute lecture that explores diffusional transformations and interfacial phenomena. Examine the driving forces behind phase transformations, including bulk Gibbs energy changes, and understand the barriers that influence these processes such as interfacial energy and strain energy. Analyze nucleation rates and growth rates as key parameters in transformation kinetics, and discover how impingement affects the overall process. Investigate the relationship between diffusion mechanisms and defects in materials, and develop a comprehensive understanding of how these factors combine to determine overall transformation kinetics in materials systems.
