Reading Ternary Phase Diagrams in Materials Science (Part 4: Intermediate Compounds)

Most engineering materials are composed of at least three different components. Their stability and response to temperature changes can be mapped and understood using a Ternary Phase Diagram. These tutorials explain how to read and interpret ternary phase diagrams, with a focus on materials science applications. The tutorials assume prior undergraduate-level knowledge of binary phase diagrams. They cover methods for representing solid-state equilibria, changes that occur during melting, and how to quantify crystallization/solidification paths for a ternary liquid. In this fourth video, we introduce intermediate compounds and demonstrate how accurately labeling the primary phase fields in the ternary system helps identify the invariant reactions in the liquidus projection. We also explain and quantify examples of crystallization paths. Notes on the video content can be found here: https://drive.google.com/file/d/1mDOr...
