Description	In the paper the results of the theoretical and experimental study of behaviour of mischmetal and non-ferrous metals in steels will be presented. The samples of two special steels were prepared with micro-alloying of mischmetal by application of plasma metallurgy. Microstructure (light optical microscope, SEM), X-ray EDX chemical microanalysis, and Instrumental Neutron Activation Analysis (Research Centre Řež) were obtained. Cerium addition resulted in the formation of micrometer size inclusions which can be utilized for controlling the grain size structure of steel castings. The majority of the particles have settled at the bottom part of the sample, indicating that the convection flow during solidification was very weak. The rare-earth metals (REM) addition slightly diminished hardness of the steel. A segregation phenomena in the distribution of cerium in the volume of special steels after relatively quick crystallization process was found.
