Mirror plane is a plane bringing a point lattice into self-coincidence with its mirror reflection in the plane. miscibility gap Dome-shaped two-phase field where two liquids L1 and L2 see binodal Figure or two isomorphous solid solutions a 1 and a2 are present see Figure . The boundary of the field is known as binodal. The transformations L L1 L2 or a a1 a2 can be considered as the occurrence of immiscibility in the liquid or solid state respectively. Because of this the field under the binodal is named a miscibility gap. FIGURE Binary diagram with a miscibility gap in the solid state a1 and a2 denote a solid solutions of different compositions. misfit dislocation In partially coherent boundaries a dislocation that compensates lattice misfit see Figure . There are at least two systems of Phase boundary D FIGURE Partially coherent phase boundary with a misfit dislocation D scheme . 2003 by CRC Press LLC mirror plane One of the macroscopic symmetry elements.
