Long period structures of the Mg base laves phases derived by the method of the classical lattice gas model

Layer structures are characterized by arrays of the c‐ and h‐sequences, so they may be assumed as one dimensional alloys of c and h. The method developed by Kaburagi and Kanamori for the determination of the structure of the ground state is applied on the linear chain alloy. The stable region for each structure has been determined in a four dimensional mathematical space which is defined by the four inter‐layer pair potentials. It has been found that the stacking variants of the Mg base laves phase correspond to successive changes of the apir potentials.
