Thermodynamics of Materials: Foundations of Phase Equilibria and Alloys

Why do materials behave the way they do under different temperatures and pressures? Understanding the thermodynamic forces behind phase transformations is the key to designing the next generation of alloys, ceramics, and advanced engineering materials. This text-only course provides a clear, step-by-step pathway to mastering the energetic principles that dictate material structure and stability. Through structured written explanations and practical examples, you will learn how to transition from basic thermodynamic laws to predicting real-world material behavior. You will gain the skills needed to analyze phase diagrams, interpret chemical equilibria, and understand the stability of solid and liquid solutions. What you'll learn: - Learn the foundational laws of thermodynamics applied specifically to materials systems. - Understand phase equilibria, unary and binary phase diagrams, and how to interpret them accurately. - Analyze the thermodynamics of solutions, including ideal, regular, and real solution models. - Practice calculating free energy changes to predict whether a phase transformation will occur. - Explore the thermodynamic driving forces behind microstructural evolution and reactions. - Discover how modern computational thermodynamics, such as the CALPHAD approach, is used to design complex alloys. The course begins with core definitions, thermodynamic laws, and state functions before guiding you through solution chemistry, multi-phase equilibria, and modern computational materials design. It is designed specifically for beginners, engineering students, and junior metallurgists, requiring no advanced prior knowledge of thermodynamics.
