Phase Diagram
A Phase Diagram is like a map that materials scientists and engineers use to understand how materials behave under different conditions, such as temperature and pressure. Think of it as a recipe book that shows when a material will be solid, liquid, or gas, and how different ingredients (elements) mix together. Companies use this knowledge to make better products, from stronger steel for construction to more efficient computer chips. When you see this term in a resume, it usually means the person knows how to select and work with materials to get the best properties for specific industrial applications.
