Abstract

The possibility of separate eddy current control of the properties of intermetallic TiAl alloy parts obtained using additive technologies is analyzed. The calculation of the signal change was carried out using the developed mathematical model for cases of changes in the electrical conductivity of only the surface layer, only the substrate, and the entire control object. It is established that in order to achieve the necessary stability of solving the system of equations for obtaining depth properties, the lower frequency should be less than 300 kHz, and the high frequency should be more than 600 kHz.
