Solid solutions

From GAWDAwiki

Solid solutions are solid phases containing more than one component and are the basis of the ability of metals to form alloys. There are two general classes of solid solution: "substitutional" and "interstitial." Substitutional solid solutions are those in which the solute atoms are substituted for solvent atoms in the crystal structure. Interstitial solid solutions are those in which the solute atoms occupy interstices in the crystal structure of the solvent.^[1]
