Abstract

PURPOSE:To obtain the ratios of the heterogeneous parts of structures and their effective crystal grain sizes and let be reflected in processes by letting ultrasonic waves of frequencies lower than the critical frequency satisfying Rayleigh scattering conditions up to high frequencies and measuring the ultrasonic wave damping constants.
