Information × Registration Number 0220U104151, 0120U104793 , R & D reports Title Thermodynamics of melts and phase transformations in multicomponent systems of transition metals as a scientific basis for the development of amorphous alloys. popup.stage_title Head Turchanin Mykhailo A., Доктор хімічних наук Registration Date 14-12-2020 Organization Donbass State Engineering Academy popup.description2 Subjects of investigations: melts of the Co–Ni–Ti system, thermodynamic properties of phases and phase equilibria of the Co–Ti system. Objectives: experimental study of the enthalpies of mixing of liquid Co–Ni–Ti alloys, description of the concentration dependence of the enthalpy of mixing of Co–Ni–Ti melts within mathematical models, preparation a dataset on thermodynamic properties of phases and phase equilibria for assessment of Co–Ti system within CALPHAD-method. Research methods: high-temperature isoperibolic calorimetry, mathematical models of thermodynamic properties of melts. Results: the partial mixing enthalpy of titanium was experimentally investigated and the values of the integral mixing enthalpy of the components of the Co–Ni–Ti melts were tabulated; the parameters of polynomial models of concentration dependence of isotherms of partial mixing enthalpy of titanium for investigated sections of the Co–Ni–Ti system are determined; the parameters of the Redlich-Kister-Mujianu model of the concentration dependence of the isotherm of the integral enthalpy of mixing of Co–Ni–Ti melts at 1873 K on the whole concentration triangle are determined; a set of consistent data on the thermodynamic properties of melts, intermetallic compounds and phase equilibria was obtained for the thermodynamic description of the Co–Ti system within the CALPHAD method. Range of application: fine metallurgical synthesis; development of new technologies for synthesis of amorphous and high entropy alloys; research and development in the field of materials science.
