Conclusions
We have shown that ultrasonic vibration with an amplitude of 20 μ and 12 μ at 250°C favors the decomposition of the austenite in KhVG steel, fragments the microstructure of the steel, and increases its hardness. Ultrasonic vibration of the same amplitude does not induce any significant changes in the steel at 200°C.
