摘要

Using average velocity measurements to estimate average profile temperature shows promise and merits further investigation. The current generation of electromagnetic acoustic transducers (EMATs) can transmit and detect signals in steel below the magnetic transition temperature. Techniques for calibrating ultrasonic velocity to internal temperature need further development. EMATs are inadequate ultrasonic transmitters for these applications. A high-energy, pulsed laser capable of generating more intense ultrasonic signals should be investigated as a transmitter. Recommendations are given for further work.
