Abstract—An algorithm for calculating the boundaries of a melt for the preparation of homogeneous crystals
A is considered. The boundaries are determined in constructing a ternary alloy involving an A_mC + B peritectic
reaction. The calculations are performed based on models of the surfaces of primary crystallization of compo-
nents A and B. Regions with different prehistories of coexisting crystals are projected onto poly- and isothermal
sections of the phase diagram.
