Resumo: An eddy current method was applied to evaluate amount of a sigma phase in a duplex stainless steel. In the preliminary experiments several transducers configuration were considered. The performance of the transducers were verified utilizing samples having different amount of sigma phase. The configurations presenting the greatest possibility of evaluation of the sigma phase were chosen for further experiments. In this paper a dedicated transducer operating in differential mode is presented. The results are shown and discussed.
