You could try asking on sci.techniques.testing.nondestructive or
sci.materials. The methods used for detecting cracks are ultrasound or
eddy current testing for buried cracks, or magnetic particle testing
(only for cracks which reach the surface). To use x-ray techniques for
crack detection you have to know the orientation of the crack you want
to detect.
