The research data of modifiers influence on the properties of Ni-hard cast iron are shown in this article. Two types of modifiers were used: mishmetall MC50Fe3 and complex modifier Spherolite-P. Melting was carried out on a laboratory induction upgraded furnace UIP-25. At the end of the melting, the hardness, wear resistance and the microstructure of the samples were investigated. Studies have shown that data processing with modifiers leads to the appearance of a certain amount of nodular graphite in the structure, which explains the increase in wear resistance with a slight drop in the hardness of the experimental alloys.
