Most engineering materials consist 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 their relevance to materials science.
The tutorials assume prior undergraduate-level knowledge of binary phase diagrams. They cover various methods for representing solid-state equilibria, the changes that occur during melting, and how to quantify crystallization/solidification paths in a ternary liquid.
In this third video, we utilize space diagrams and liquidus projections to describe 4-phase ternary invariant equilibria. We explain how to identify ternary eutectic and peritectic reactions and predict the crystallization paths for different compositions.
