Journal of Engineering Physics and Thermophysics Aims and scope

The results of Stefan problem-based calculations of the distribution of nonstationary temperature fields in the surface layer of iron samples exposed to compression plasma flows at the given initial and boundary conditions are presented with account for the temperature dependence of the heat capacity and thermal conductivity of a sample. It is shown that on ultrafast heating and cooling (~107 K/s), an iron sample exhibits a modified layer having a nonequilibrium microstructure and containing amorphous and nanocrystalline phases that increase its strength and wear resistance.
