摘要
The laser ultrasonic technique has been used to determine grain sizes in Interstitial Free (IF) steels. With an analysis method that employs scattering theory, absolute values of the average grain size have been calculated directly from the ultrasonic traces. These results indicate that the laser ultrasonic technique may be incorporated on-line for direct measurements of grain size during steel production.
