Abstract

PURPOSE:To obtain the size of the effective crystal grains of steels and obtain reliable data by letting the ultrasonic waves of a frequency range wherein the damping of the ultrasonic waves by Rayleigh scattering occupies the majority be propagated into the steel specimen and measuring their damping constants.
