| Research Abstract |
A new noncontact ultrasonic method for monitoring 3-D temperature profiles of heated materials has been developed and its feasibility in materials process monitoring at high temperatures has been demonstrated. At first, the accuracy in temperature determination using the developed thermometry is examined theoretically and experimentally. The use of a shear wave is then proposed to improve the measurement accuracy in the ultrasonic thermometry and its effectiveness of using shear wave in the ultrasonic thermometry is successfully demonstrated. Furthermore, a laser-ultrasound method for monitoring temperature distributions of rotating objects has been proposed and the feasibility of the method for monitoring both surface and internal temperature distributions of a rotating steel cylinder during heating are demonstrated. In addition, casting process monitoring using the ultrasonic thermometry is examined experimentally. Thus, it is highly expected that the ultrasonic thermometry is a promising means for on-line temperature profiling of industrial materials processed at elevated temperatures.
