The study of the formation of copper-nickel deposits, optimization of the processes in metallurgy of copper, nickel and cobalt, the production of new compounds with various properties have a physicochemical basis and can be solved through obtaining the accurate and reliable information on phase equilibriums within the four-component Fe-Ni-Cu-S and Fe-Ni-Co-S systems as well as their ternary boundary systems [2-4]. We had elaborated 3D computer models for T-x-y diagrams of real systems and for their prototypes with the expanded borders between the phase regions and afterwards we have printed 3D-puzzles of the exploded phase diagrams with the phase regions and with the clusters of phase regions as its elements. After the verifying of information on the bounding ternary systems, the assembling of the four-dimensional T-x-y-z diagrams has been completed. The methodology, which has been successfully developed by the authors for a long time, includes a comprehensive approach implemented in several stages: 1) to develop a prototype (4D computer model) of T-x-y-z diagram for a four-component system, based on knowledge about boundary systems and basic phase interactions within the volume of the system under study; 2) to obtain sufficient and reliable experimental data in a wide range of concentrations and temperatures; 3) to refine the T-x-y-z diagram prototype of the study system, taking into account the experimental results obtained. This work was been performed under the program of fundamental research SB RAS (project 0270-2021-0002). References: 1.
