intermetallic compound

(in'tĕr-me-tal'ik kom'pownd),
a metal mixture that has a fixed chemical composition, or a narrow range for its composition when cooled from the liquid state. The atoms of one metal occupy definite positions in relationship to every point on the space lattice.

(in'tĕr-me-tal'ik kom'pownd)
Phase formed on cooling of liquid metal solutions wherein the resulting phase has fixed chemical composition or narrow range of compositions.
