    Femtosecond laser processing of tungsten monocarbide alloy cutting tools
    (MDPC Publishing, 2024-09) Бруяка, Ольга Олегівна; Bruyaka, Olga Olehivna
    Nanostructured materials with extremely fine grain sizes are known to have unusually high strength and toughness, higher diffusivity, beneficial sintering properties, and other characteristics that enhance the performance and reliability of tungsten monocarbide alloy part designs. This article presents the mechanism of formation of nano and subnanolayers and the influence of nanostructure on grain growth within the nanometric range have been revealed. The possibility of processing an alloy of tungsten monocarbide with a femtosecond laser beam has been demonstrated in order to form a nanostructured layer with fairly small grain sizes (about 10 nm), which can radically improve the properties of this alloy and ensure high performance and efficiency of its operation.
