Method of ultrasonic measurement of textureIowa State University Patents
AbstractA method for measuring texture of metal plates or sheets using non-destructiveultrasonic investigation includes measuring the velocity of ultrasonic energy waves in lower order plate modes in one or more directions, and measuring phase velocity dispersion of higher order modes of the plate or sheet if needed. Textureor preferred grain orientation can be derived from these measurements with improves reliability and accuracy. The method can be utilized in production on moving metal plate or sheet.
