Paper Abstract

Contribution of diode laser remelting of high speed steels of grades: HS 2-10-1-8, HS 6-5-2 and HS 10-2-5-8 on microstructure, chemical composition, hardness and cutting performance was under examinations. Increase of hardness was observed in laser remelted zone in comparison to the conventional heat treated steels. Microanalysis SEM EDS showed differences in chemical composition in chosen regions of not treated and laser treated materials. Laser remelting caused the structure refinement and increase of the wear resistance, however, the cutting performance was diminished in respect to the steels not subject to the laser modification. Residual stresses using X-ray method were measured both in steels after conventional heat treatment and subjected to the laser modification.
