- The surface layers of low-carbon steel metal subjected to shot peening were studied. The velocity of Rayleigh surface waves of various frequencies in the range of 3-9 MHz by the phase-pulse method using contact piezoelectric transducers measured. The study of the distribution of residual mechanical stresses in depth was carried out using the etching of the surface layer of the metal and the use of a strain gauges. The characteristics of the roughness of the surface layer of the metal, which has arisen as a result of shot peening, have been determined. The effect of roughness and plastically deformed layer on the velocity of surface acoustic waves (SAW) is estimated by the method of layer-by-layer grinding of the surface layers of the metal. Based on the determination of the magnitude of the residual mechanical stresses and the known acoustoelastic coefficients, the magnitude of the change in the velocity of SAW under the action of these stresses is estimated.
