Progress in eddy-current non-destructive evaluation of conductive materials

摘要

Recent progress in eddy current non-destructive evaluation is discussed. The basic principle of the method is shortly explained and its possible applications in non-invasive evaluation of conductive materials are summarized. The main aspects connected with application of the method in practice are described in details together with actual issues of research and developments. Special attention is paid to eddy-current testing probes and to the evaluation of an indicated defect from eddy-current testing signals. Authors' group activities in this field are presented on the basis of the reported current state-of-the-art.
