Abstract

Processing by the aerodynamic sound hardening method, based on high-energy low-temperature of energy impact created by the resonant effect of acoustic waves in the sound frequency spectrum, high-speed steel R6M5 eliminates the structure error in the form of stitching in the form of carbide phases oriented along the deformation axis due to the decrease in structural anisotropy, phase hardening occurring to the relaxation of structural stresses,
dislocation density, reduces the size of primary carbides from 7…15 to 3…8 μm and reduces their number by 1.6 times, which significantly improves the uniformity of the Р6M5 (W ≈ 6 %; Mo ≈ 5%) steel structure.
