摘要:
The use of the ultrasonic pulse technique as a means of measuring ultrasonic absorption in an aluminum alloy (2S) at high temperatures has been considered. The absorption for both the longitudinal and shear waves was computed. These measurements show that the absorption is relatively constant up to approximately 200°C where it then experiences a large increase. The major part of the absorption at high temperatures is found to be due to thermal effects.
