Measurements on High-Temperature Steelses, pipes, ...) are heated over 1000°C for thermomechanical processing while being moved at high speeds. Tight control of dimensions and qualities requires the on-line and noncontact/nondestructive assessment of interior conditions of intermediate products. Sensing should not perturb the process. Pr

Average Grain Size of Steels 1970). Many techniques have been studied for nondestructive evaluation of grain size, including ultrasonic attenuation (scattering), X-ray diffraction, and magnetic tests. Among them, ultrasonic attenuation is the most promising, because it provides a through-thickness average of grain structure, o

One of major subjects of acoustoelastic studies has been the separation of the stressinduced anisotropy from the intrinsic anisotropy.
