The paper presents numerical model of thermal phenomena, phase transformation and mechanical phenomena associated with hardening of carbon steel C80U. The stresses generated during hardening were assumed to result from thermal load, structural plastic deformations and transformation plasticity. The hardened material was assumed to be elastic-plastic, and in order to mark plastic strains the non-sothermal plastic law of flow with the isotropic hardening and condition plasticity of Huber-Misses were used. Thermophysical values of mechanical phenomena dependent on both the phase composition and temperature. The numerical simulations of hardening processes of axisymetrical object after full austenitisations were performed.
