Abstract

The design of the primary transducer with an H-shaped yoke for a differential magnetic structuroscope (DMS-5) has been optimized for non-destructive testing of residual austenite (RA) content in ferromagnetic steels. Numerical simulation using the finite element method was performed to analyze the magnetic flux distribution in the H-shaped magnetic core, and the optimal gap dimensions for mounting a Hall-effect sensor as the sensing element were determined. Experimental results confirmed a twofold increase in sensitivity of the new transducer design compared to the previous version, enhancing the reliability of non-destructive phase composition analysis in ferromagnetic steels. A linear relationship was established between the output signal of the DMS-5 transducer and RA content in the range of 9—18 % in the tested samples.
