The non-equilibrium thermodynamics analysis of the eutectoid transformation in carbon steel is performed. Onsager’s equations of motion are obtained for the model thermodynamic system describing eutectoid transformation. Dependences of basic kinetic parameters of process–interplates distance and rate of pearlite growth–on the magnitude of steel supercooling are calculated for the stationary process of eutectoid transformation.

Key words: non-equilibrium thermodynamics, equations of motion, eutectoid transformation, diffusion, carbon steel.
