Obtaining of new scientific information on the constitution of phase diagrams (or their fragments) of the ternary systems Ti–Hf–Ni (Cu), Ti–Nb–Mo, Ti–Fe–Sn, Ti–Ru–Rh, Ti–Rh–Ir, Zr–Nb–Al (in the range up to 50 at.% Al), Zr–Sc–Ni (in the range up to 50 at.% Ni), Cr–Co–Al (in the range of 70–100 at.% Al), Cr (Co)–Fe–B (in the range up to 50 at.% B), Fe–Co–Er; quaternary systems Ti–Zr–Nb–Mo and Hf–Ru–Rh–Ir; thermodynamics of phases in the binary and ternary systems formed by REM, transition metals and p-elements (Bi–Tm, Bi–La (Nd, Gd)–Ni, Pb – Eu (Yb), In–Tb systems, In–Tb–Ni, In–Sr (Ca), Al–Tb, Al–Tb–Ni, Al–Er and Al–Er–Ni), determining the laws of physico-chemical interaction in quaternary systems formed by aluminum with 3d metals of groups IV-VI (titanium, vanadium, chromium) and d-metals of groups VI-VIII, analysis of the topology of phase diagrams of this class systems and possibilities of practical application of the received data. These data will form a scientific foundation for the development of new alloys for various applications (structural alloys, functional materials with special properties, materials for nuclear energetic) and will allow to formulate criteria for selection of alloys with the predicted level properties and proposals for technologies of their production.
