Abstract

The paper proposes an experimental method of material inspection, which is based on digital processing of multi-frequency eddy current measurement data. The influences of various factors (conductivity, the gap between the sample surface and the sensor, the thickness of the sample) on the obtained hodographs are examined by taking the aluminum alloys for example, and the possibility of separation of various factors is analyzed. The results obtained are indicative of how much promise the proposed method offers for the inspection and testing of products made of aluminum alloys.
