Abstract
Studies of ultrasonic wave velocities in commercial steel sheet products have been made and the results have been interpreted in terms of crystallographic textures measured by X-ray diffraction. Elasticity tensors were calculated as weighted averages of the Voigt and Reuss bounds using texture coefficients together with single crystal stiffness data, and these were then employed to predict the ultrasonic wave velocities. For guided bulk waves of types So and SHo excellent agreement was obtained between measured and predicted values. The application of these types of measurements to process control in metallurgical annealing lines has been briefly discussed.
