Especially the structural sensitivity of the magnetic parameter, i.e. coercive force, the electric parameter, i.e. specific electric resistance and the heat parameter, i.e. thermal conductivity factor were thoroughly studied. The necessity of experimental survey on real samples with different microstructures for determination of empirical dependence between informative parameters and properties that characterize material microstructural state and its physical and mechanical characteristics, was approved. Three experimental samples (supply condition, annealed and hardened) with different microstructures to conduct field comparative survey, were produced. Metallographic analysis to determine microstructure was carried out in these samples.
