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

Marketing und Innovationsmanagementrequency response of the amplitude, or the resonance spectrum, thus includes many resonance peaks. The resonance frequencies are then used in an inverse calculation to find the set of elastic constants that give the measured resonance frequencies.

On-Line Texture Monitoring of Steel Sheetsltrasonic-velocity changes and their anisotropy caused by stress, and is capable of measuring residual stress nondestructively (Chapter 10). One of major subjects of acoustoelastic studies has been the separation of the stressinduced anisotropy from the intrinsic anisotropy.
