Nondestructive Evaluation Methods for Composites: Ultrasonic Measurements and Image Analysis Application on Testing in Extreme Conditions
This article deals with nondestructive testing methods such are ultrasonic measurements and image analysis as applied to the thermal stability testing of materials. Image analysis is also used to determine damage to the surface during the cavitation resistance testing. Possibilities of the used nondestructive methods and results of their application are discussed on the basis of the obtained results for low cement, high alumina castables. Keywords: nondestructive methods; ultrasonic measurements; image analysis; thermal shock; low cement high alumina castables
