Abstract: On the basis of the accumulated scientific research experience, the authors formulated a methodological approach to the selection and purpose of modes of hardening heat treatment of powder high-speed steels. It is proposed to designate the modes of hardening heat treatment of high-speed steels, taking into account the operating conditions of the tool and on the basis of the results of comprehensive quality control of steels in terms of basic properties - hardness, heat resistance, impact toughness and microstructure parameters - carbide heterogeneity, grain size at various technological stages.

Key words: Powder high-speed steel heat treatment quality methodological approach micro-structure basic properties heat resistance
