Abstract:
A new approach to assemble a three-dimensional (3D) computer model of the T-x-y diagram is demonstrated on the example of the Ag-Au-Sb system. It is based on the assembling of phase diagram from the surfaces and the phase regions. Its first variant (template) permits to design the 3D model even in the absence of some important data. Further, the template becomes the precise model, when new data are discovered. As a result, the obtained 3D computer model makes it possible to construct any iso- or polythermal section, to calculate mass balances for the arbitrarily taken compositions and even to find errors in the interpretation of experimental data. T-x-y diagram Ag-Au-Sb consists of 78 surfaces (5 liquidus, 5 solidus, 36 ruled surfaces, 16 solvus, 16 horizontal simplexes of the 4 complexes in accordance with the invariant reactions) and 40 phase regions (5 L+I, 5 I, 7 L+I+J, 8 I+J, 5 I+J+K, where L – liquid and I, J, K – solid solution Ag(Au), Sb, compound AuSb2 and two phases of variable concentration in the Ag-Sb system).
This work has been performed under the program of fundamental research SB RAS (project 0336-2014-0003) and was partially supported by the Russian Foundation for Basic Research (projects 14-08-00453, 15-43-04304).
