    Zmena mechanických vlastností vybraných materiálov aplikáciou povrchového kalenia
    (University of Žilina, 2024) Fabian, Peter; Jaššo, Martin; Pastirčák, Richard
    Comparing the mechanical characteristics of steel used in the weapons sector to make barrels for short, small arms is the study's goal. The heat treatment of representative samples resulted in their hardening, surface hardening to a specific layer thickness, and tempering. It has not yet been thoroughly examined how the thickness of the hardened layer affects the modification of the mechanical characteristics of the chosen materials. Surface hardening is widely regarded as one of the methods for producing a resistant core and a hard surface on a component. Nonetheless, the overall material's mechanical characteristics alter in tandem with the layer's thickness. The outcomes of this study will also be useful for the induction heat treatment of other similar material components.

    Tepelné spracovanie nástrojových ocelí
    (University of Žilina, 2024) Fabian, Peter
    The article describes the importance of heat treatment of tool steels, referred to as class 19. To obtain the required properties of steels, their chemical composition alone is not enough. An irreplaceable role is also played by subsequent processing, be it thermal, chemical, or a combination chemical-thermal or thermo-mechanical processing. With the right settings processing, the desired properties are achieved, and the service life of the steel is also increased.
