By the end of this tutorial, you should have an understanding of:
Many materials are mixtures, even if they only have a trace of impurity. But some materials are deliberately made as mixtures, to give better properties and/or costs.
Phase diagrams are maps of phase equilibria. To predict the structure of a metallic alloy or ceramic, a materials engineer will first look at the phase diagram. It shows its structure at equilibrium which will allow its properties to be predicted.
