The diffusion phase transformation process described by a nonlinear system of partial differential equations with a moving boundary has been considered. The inverse problem is formulated to determine the solute concentration on the external surface of the volume under consideration, which ensures the moving boundary displacement according to a given law. Applying the methods of fronts rectification and difference approximation, the problem posed is reduced to two difference problems. A computational algorithm is proposed for solving the obtained difference problems.
