In the paper the new approach of thermal treatmen is presented, namely the deep cryogenic treatment which affect the properties of high speed steel. The results are very important for tool industry.
F.01 Acquisition of new practical knowledge, information and skills
COBISS.SI-ID: 742570Tribological tests indicate that deep-cryogenic treatment contributes to improved abrasive wear resistance and better galling properties of P/M high-speed steel. However, austenizing temperature is a very important parameter, which defines the level of possible improvement.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 742314The fraction of martensite was estimated using band-contrast images, while the fraction of carbides was calculated using the crystallographic data.
