Ultrasonic (US) wave velocity measurements associated with adapted polycrystalline models of plastic flow are used to evaluate the texture and strain ratio r(α) of steel sheets. Results are compared with more classical destructive techniques (X-ray, tensile tests). A satisfactory agreement is obtained providing that US data are made consistent by the appropriate algorithm proposed.
