Description

The ultrasonic inspection of austenitic castings and welds is often complicated by their material structures. These steels are characterized by large grains, sometimes comparable in size with typical ultrasonic wavelengths. Such coarse macrostructure can lead to high ultrasonic attenuation, significant grain noise and to anisotropic properties [1]. Furthermore, austenitic welds may solidify as large columnar grains, with orientations which are slowly varying throughout the weld. These materials are then inhomogeneous as well as anisotropic.
