Nondestructive Evaluation of Materials

The book concentrates on X-ray, sonic, optical, and magnetic nondestructive testing methods. Papers were presented on X-ray diffraction methods, detection of fatigue damage by X-rays, residual stress measurement by X-rays, neutron radiography, electromagnetic ultrasonic transducers, acoustic interactions with internal stresses in metals, image processing, quantitative magnetic methods, and penetrant inspection.
