The paper describes the effect of laser traverse speed during laser hardening on hardness and micro-structure. The experimental material is hot work tool steel AISI H11 with samples sized 100×100×35 mm. The initial state of the material before laser hardening is quenched and tempered. The laser hardening temperature is constant at 1100 °C, selected laser traverse speed was 1, 2, 4, and 6 mm/s. A numerical simulation performed in DEFORM-3D software before the experiment showed tendencies of temperature displacement and expected course of hardness. Increasing traverse speed leads to de-creased laser-hardened depth and decreased hardness drop in the heat-affected zone (HAZ). The ex-perimental program confirmed the results of the numerical model. The differences in the microstruc-ture were investigated by light (LM) and scanning electron microscopes (SEM), which revealed an evident difference between the surface area and the locality with the lowest hardness. Local differ-ences from the perspective of presence of carbides were analysed by energy dispersive spectroscopy (EDS). This investigation was performed to optimize laser traverse speed to improve the subsurface hardness profile, which is essential for the lifetime and reliability of forging dies.
