This book provides a comprehensive exploration of the fundamental principles of thermodynamics and kinetics in materials science, offering a balanced integration of theoretical frameworks, computational methodologies, and real-world applications. Covering both equilibrium and non-equilibrium thermodynamics, it introduces key concepts such as thermodynamic laws, phase diagrams, reaction kinetics, and transport phenomena.A distinctive feature of this book is its dedicated coverage of computational thermodynamics and kinetics, including CALPHAD modeling, Monte Carlo simulations, phase-field methods, and coupled thermodynamics-kinetics approaches. These topics are critical for understanding the behavior of materials in complex, real-world conditions. Additionally, the book examines capillarity-driven morphological evolution, microstructural coarsening, and diffusion mechanisms, all of which are fundamental to material design and processing.Designed as a textbook for undergraduate and graduate students, as well as a reference for researchers and professionals, this book provides a structured approach to mastering thermodynamics and kinetics in materials science. The integration of theoretical foundations with computational techniques ensures that readers develop a robust, application-oriented understanding of the subject.
