Detection and characterisation of defects in highly scattering materials using ultrasonic arrays

Coarse grained materials are widely used in the power generation industry and their inspection is critical for the safe operation of nuclear power plants. Ultrasonic array imaging is an important non-destructive testing method which is capable of detecting and characterising defects in a component. However, the performance of ultrasonic inspection can be severely affected by the existence of grains in a polycrystalline material which cause...
