Abstract
The preferred grain orientation in polycrystals causes a direction dependence of the ultrasonic wave
velocities. In an extensive study, the texture influence on different ultrasonic wave velocities is
measured in series of cold-rolled ferritic steel sheets. Based on that, ultrasonic techniques are
developed to characterize the texture in terms of the three fourth-order expansion coefficients of the
orientation distribution function (ODF). Evaluation equations are given for the application of free
ultrasonic longitudinal and shear waves as well as for the application of ultrasonic SH-waves.Furthermore, linear correlations are found between the
