Abstract
A new instrument for rapid measurement of changes in ultrasonic velocity in a material has been developed. The changes in velocity are recorded automatically with the time difference between reflection and transmission waves. The minimum recording interval is 1 ms. The relative accuracy is from 10−3 to 10−4 for the velocity change in a sample length of about 6 mm. Two applications are reported.Keywords
