Beschreibung
Zusammenfassung:	The subject matter of the invention is a method of heat treatment of medium- and high-carbon alloy steels, the AIM of which is to produce a fragmented, multiphase microstructure consisting of tempered bainitic ferrite and martensite, separated by layers of stable residual austenite and finely dispersed alloy carbide precipitates responsible for secondary hardness. The method according to the invention makes it possible to control the phase fraction and morphology of the microstructure, allowing achieving the desired properties of the steel in terms of applications and requirements for tools and structural components. The method according to the invention, can be used to shape the properties of pieces that are required to have higher impact strength and resistance to fracture compared to conventional martensitic quenching and tempering treatment, while maintaining comparable hardness and strength. These pieces can include industrial knives, coin punches and punching dies for plastics, among other things. This treatment allows for longer life of the pieces and increases the fault-free life of equipment.
