description: The subject of the graduate qualification work is âInvestigation of the effect of adding yttrium in the selective laser melting of a nickel superalloyâ. The given work is devoted to studying possibility of improving the characteristics of nickel alloys. The research set the following goals: Study of the peculiarities of the effect of adding yttrium in selective laser melting. Investigation of the structure of specimens of a nickel superalloy during selective laser melting with the in-situ addition of yttrium. Revealing the characteristics that were affected by the introduced REM in the obtained samples. Study of the strength and ductility characteristics of samples. The paper studies the possibility of improving the characteristics of nickel alloys, such as strength and ductility. For this purpose, in-situ synthesis of powders of nickel superalloy and rare-earth metal yttrium was carried out in the process of selective laser melting. Preliminary studies show that the introduction of REM into the alloy can increase the strength characteristics. Studies of the microstructure and chemical composition were carried out, obtained on a scanning electron microscope (SEM). Etching was carried out with a reagent based on CuSO4, H2SO4, and HCl. Studies of mechanical properties in tension were carried out on a tensile testing machine. To conduct microstructural studies and establish mechanical characteristics, the samples were subjected to heat treatment.
