investigating the effect of the deep cryogenic heat treatment on the mechanical properties and corrosion behavior of 1.2080 tool steel

deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the finaltempering treatment to enhance the wear resistance and hardness of the steels. in this study, the effects of thedeep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studiedusing the wear testing machine and polarization and impedance spectroscopy tests. moreover, the microstructuralchanges of the deep cryogenically treated samples were clarified via the scanning electron microscope (sem)and x-ray diffraction testing machine. the results showed that the deep cryogenic heat treatment eliminated theretained austenite and made a more uniform carbide distribution with higher percentages. beyond this, it wasclarified that the deep cryogenic heat treatment increased the hardness and improved the wear behavior of the1.2080 tool steel, as well as decreasing the corrosion resistance, due to the higher chromium carbides producedduring the deep cryogenic heat treatment.
