Fracture resistance of low-alloy steels 15KH1M1F, 25KH1MF, 25KH1M1F, 20KH1M1FTR and steels 20KH13, 15KH11MF, 15KH12VNMF without and with thermomechanical treatment under intense cavitation on the sample surface was investigated. Cavitation was generated by exponential-profile ultrasound emitter. The emitter end surface varies with the frequency of 20 kHz and amplitude of 30±2 microns. Erosion measurements of samples were conducted by gravimetric method. Measurement accuracy was ±0,015 mg. According to the measurements, the dependences of the erosion on the cavitation exposure time were constructed. For quasi-linear plots of kinetic curves, the destruction rate of the samples was calculated and their cavitation resistance was determined. The...
