Quantitative characteristic of the change of velocity of a longitudinal acoustic wave and density in ferritic-pearlitic steel as a result of plastic deformation was obtained. Possibility of evaluation of the level of damage that is due to plastic deformation by the change of acoustic wave velocity is demonstrated. Experimental data were the base for correlating the change of velocity and damage level in the form of a third-degree polynomial. 14 References, 3 Figures.
Keywords: plastic deformation, damage level, acoustic wave velocity, density
