Temperature fields of surface layers during plasma-detonation treatment (PDT) of parts were determined through solving the non-stationary heat conduction equation by the finite difference method. The relationships derived were used for analysis of the kinetics of phase transformations in structure of steel U8 during PDT. The calculation-theoretical analysis results were compared with the experimental data.
Keywords: carbon steel, plasma-detonation treatment, finite difference method, non-stationary heat conduction equation, temperature fields, high rate heating (cooling), structural-phase transformations
