Title : 3D Computer Models of Isobaric Phase Diagrams for Ternary Systems to Verify and Validate Thermodynamic Calculation and Experimental Investigation: Ag-Bi(Sb)-Sn, Al(Bi)-Sn-Zn, Au-Ge-Sn

Abstract:

The assembled 3D computer models of isobaric phase diagrams (PD) for ternary systems permit to verify and validate the data on phase equilibriums and to design the microstructures of heterogeneous material, including the materials genome decoding. The project “PD as an Advanced Tool of Materials Science”, http://ipms.bscnet.ru/labs/skkm.html , is focused on the following topics: concentration fields of different dimension with the different solidification schemes and microstructures, correction of PD graphics, multi-component systems polyhedration, 3- and 4-phase regions with the reaction type changing, competition of crystals with different dispersion in the invariant regrouping of masses, mathematical approximation of PD, assembling of PD computer models, 3D prototyping of the phase regions and concentration simplexes for the exploded PD and for the concentration complexes of the reciprocal quaternary systems, simulation of DTA spectra and X-ray analysis spectra in the training programs for specialists in the field of physics-chemical analysis. Computer models of PD are the wonderful addition for the thermodynamically assessed experimental PD. There are great tasks to digitalize the phase equilibriums data for the multicomponent systems and there are many advices, which way to teach and to learn the language of multidimensional phase diagrams. In addition to these advices, we propose to elaborate the 3D and 4D computer models for the isobaric PD of ternary systems. And to prototype the exploded T-x-y diagrams by a 3D printer.

This work was been performed under the program of fundamental research SB RAS (project 0270-2021-0002).
