Abstract
A technique for measuring the index of nonlinearity of a probing signal is proposed, and an ultrasonic device to implement this technique is described. The high sensitivity of the measured index to metal damage is shown. The characteristics of the device make it possible to use it as a means of nondestructive testing of metal in production conditions at industrial facilities.
