This study proposes a novel nondestructive evaluation method of chill contents in gray cast irons by means of AC magnetization method. For the purpose, magnetic properties of cast irons w ith different chill contents were evaluated by B-H loop analyzer. Results were discussed in view of matrices and graphite, and it was found that some magnetic parameters, especially B-H l oop area, correlate well with ratio of cementite area to graphite one. Focusing on the fact, AC magnetic method was applied to evaluati...

This paper proposes a methodology of lift-off measurement using optical system embedded in Eddy Current Testing (ECT) system. Firstly, the influence of lift-off on ECT signal was evaluated. Secondly, both ECT signal with lift-off shifting and the lift-off signal were acquired by means of an ECT probe with an optical displacement sensor. Then two cases of the crack shapes reconstructions were carried out using inverse analysis code. One was computed with taking the measured lift-off into account and t...
