| Abstract | |
| Ultrasonic techniques using an EMAT (electromagnetic acoustic transducer) for evaluating material properties were developed. Two items are described. One is the evaluation of the formability in cold-rolled steel sheets by using the S0-mode plate-wave EMAT. The other is the measurement by the stress in the rim of railroad wheels by using two polarized SH-waves EMATs. The experimental results obtained in these techniques agree with theoretical predictions, and the techniques are useful for monitoring the material properties. | |
