Reading Ternary Phase Diagrams in Materials Science (Part 5: Complex Systems, MgO-Al2O3-SiO2)

Описание

Most engineering materials are made of at least three different components. Their stability and response to changes in temperature can be mapped and understood using a Ternary Phase Diagram. These tutorials explain how to read and interpret ternary phase diagrams of interest to a Materials Scientist.
The tutorials assume some prior undergraduate-level exposure to binary phase diagrams. They explain the different methods for representing solid-state equilibria, the changes occurring upon melting and how to quantify crystallization/solidification paths for a ternary liquid.
This last video focuses how to read a “complex” ternary, MgO-Al2O3-SiO2, using the principles developed in the previous tutorials; it reviews examples of crystallization paths and reactions of different compositions and shows how the diagram can be used to fully quantify the behavior of the system.
