The purpose of this work is new and promising materials for foundry production, for which research was carried out on the above-mentioned objects. Research methods: optical microscopy, microhardness measurement, thermodynamic analysis, standard methods of studying the technological properties of molding mixtures, regression, and statistical analysis methods, CAD-CAE systems, CALPHAD-method. Research has been carried out: processes of modification of cast iron melts; properties of carbon-containing additives of sand-bentonite mixtures. The conditions of diffusion metallization of the surface of carbon steels have been established. A database of parameters of models of excess Gibbs energy of phases was created. Prediction results of the composition regions of amorphization of multicomponent melts were obtained. The scientific novelty is in: new technologies for processing cast iron melts in a foundry mold; new technology for the production of additives for sand-bentonite molding mixtures; defined for the first time conditions of diffusion metallization of the surface layer of carbon steel; a new thermodynamic description of the Fe–Ti–Zr system; for the first time predicted composition regions of amorphization of Cu–Ni–Hf, Fe–Ni–Hf, Fe–Ti–Zr, Cu–Fe–Ni–Ti–(Zr,Hf) melts. Scope: in the production of castings and in the teaching of foundry production specialists. Product Description popup.authors Ahraval Pavlo H. Vodopianova Hanna O. Korsun Vladyslav A.
