Abstract
Increasingly, developments in welded constructions means that steel plate with high resistance to lamellar tearing has to be used. An experimental programme has been carried out on 17 C/Mn Fe52D steels, to indicate what features of longitudinal wave transmission ultrasonics may be used in assessing susceptibility to lamerllar tearing. A combination of two kinds of evaluation proved promising: the contribution of matrix toughness, measured from the anisotropy of ultrasonic velocity; and the contribution of the amount of inclusions, assessed by ultrasonic attenuation measurements and inclusion counting by ultrasonic reflection. No useful results have been obtained from ultrasonic spectroscopy.
