The work presents microstructures of the remelted zone of HS 6-5-2 high-speed steel. Zones of this kind can be created as a result of treating the material with a CO2 laser beam. The laser processing parameters have been chosen in such a way that the surface layer of steel remelted. The microstructures' images were taken using a scanning microscope. The tests focused on both the directional and volumetric crystallization structures. They imply that - depending on the crystallization conditions - in the remelted zone cells, dendritic cells or dendrites may be formed.
