摘要
In this paper, an approximation technique for predicting the response of an eddy current coil in the presence of small changes in conductivity is discussed. The small changes in conductivity that are considered in this work are changes in the orientation of single crystals in polycrystalline, anisotropic materials. Data from electron backscatter imaging techniques is presented and used for the analysis. The models were run for the microstructure data and an approximation to the eddy current response is shown. This image is compared with images from actual eddy current probes and the approximations are shown to be relatively accurate compared with a previously presented model.
