FIELD: metallurgy.
SUBSTANCE: product after cold plastic deformation is subjected to pulsating subsonic air flow impact having frequency corresponding to frequency of oscillations of the product to be treated, and sound pressure of 100-145 dB at -20°C to +5°C.
EFFECT: improved reliability of cold-deformed metal products due to increased plasticity and viscosity without loss of strength and hardness, and reduced processing time.
