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.
