An issue of contact melting in binary eutectic systems in non steady mode was claimed and solved. It was proved theoretically that the boundaries of phase transformation drew according to the parabolic law. Analytical formulas determining distribution of bulk atom concentrations in solid alloys and eutectic melts were obtained.
