摘要:
We present a study performed to model and predict the ultrasonic response of alumina inclusions in steels. The Born and the extended quasistatic approximations have been applied and modified to improve their accuracy in the framework of this application. The modified Born approximation, allowing to deal with various inclusion shapes, have been selected to be implemented in the CIVA software. The model reliability has been evaluated by comparison with Ying and Truell’s exact analytical solution. In parallel, measurements have been carried out upon both natural and artificial alumina inclusions. © 2003 American Institute of Physics
