Paper Abstract

The paper presents the results of metallographic investigations, measurements of microhardness, measurements of residual streses, abration resistance of high speed steel grades, treated with continuous laser. Hs 6-5-2 and HS 7-4-2-5 steel grades in as-fabricated state annealed, remelted with a CO2 laser. After laser beam treatment the 1x2 hours tempering was applied at temperature of 560 and 590 °C. The remelting zone consists of dendritic cells and columnar crystals. Measurement of macro-stresses in laser remelting zone using Waissman-Phillips method.
