In this work, was studied the possibility of producing nickel-free stainless ODS steel using liquid metallurgy. In order to investigate the injection of dispersed yttrium oxide into steel, 5 different methods under induction vacuum melting conditions were tested. The aim of the study was to approbate the possibility of mechanical introduction of yttrium oxide powder into the martensitic-ferritic matrix of AISI 410 steel by two methods, or the possibility of oxidation of yttrium metal by 3 methods (from iron oxide, from residual oxygen in the furnace chamber, from injected oxygen into the furnace chamber). As a result of the performed work, the highest yttrium concentration of 0.0552 ppm from the oxidation of metallic yttrium during the reduction of iron oxide was recorded.
