Dubens'kyj V. Phase equilibria, crystal structure and some physical properties of compounds in the R-{Co, Ni, Cu}-In (R = Ti, Hf, Rare Earth) systems

The dissertation is devoted to the investigations of phase equilibria in the ternary systems and crystal structures and also some physical properties of intermetallic compounds. Isothermal sections at 870 K for {Ti, Hf}-{Co, Ni, Cu}-In systems have been built. The existence of 9 ternary compounds was confirmed and existence of 10 compounds was established and for 5 of them crystal structure was investigated at the first time. Existence of solid solutions on the basis of 5 binary and ranges of homogeneity of 2 ternary compounds also has been established. Crystal structure (by single crystal method) of 2 compounds in Tm-Co-In system was specified and established for new PrNiIn2 compound and was found 4 isotypic. For 3 compounds magnetic and electrical properties has been investigated. Key words: phase equilibria, crystal structure, titanium, hafnium, rare-earth, cobalt, copper, nickel, indium, magnetic properties, electric properties.
