摘要: During the last two decades, ultrasonic testing was developed as an efficient tool for materials characterization. Acoustical waves by their passage through materials, carry out a multitude of information contained in signal on mechanical and physical properties material under inspection. In this paper, experimental study steel samples has been performed to evolution some parameters such wave velocities attenuation coefficients function grains size. The results obtained are discussed analyzed order develop non-destructive technique size determination.
