Nonmetallic inclusions in magnetic alloys of the Fe – Co – Ni – Cu – Al – Ti system with additions of niobium and hafnium used in the production of single-crystal permanent magnets are studied. The kinds of inclusions in magnetic alloys are determined with the help of rapid analysis of the chemical composition, optical and electron microscopy, quantitative microscopic x-ray spectrum analysis, and electron back-scatter diffraction. The phase compositions are computed with the help of the Thermo-Calc software.
