A thermodynamic analysis of the synthesis of face-centred cubic (fcc) and body-centred cubic (bcc) solid solutions of Ti-based alloys produced by mechanical alloying was performed. Four Ti-based alloys were analysed: (i) Ti-13Ta-3Sn (at.%), (ii) Ti-30Nb-13Ta (at.%), (iii) Ti-20Nb-30Ta (wt. %) and (iv) Ti-33Nb-4Mn (at.%). The milled powders were characterized by X-ray diffraction, and the crystallite size and microstrain were determined using the Rietveld and Williamson–Hall methods. The Gibbs free energy of mixing for the formation of a solid solution of the three ternary systems (Ti-Ta-Sn, Ti-Nb-Ta and Ti-Nb-Mn) was calculated using an extended Miedema’s model, applying the Materials Analysis Applying Thermodynamics (MAAT) software. The values of the activity of each component were determined by MAAT. It was found that increasing the density of crystalline defects, such as dislocations and crystallite boundaries, changed the solubility limit in these ternary systems. Therefore, at longer milling times, the Gibbs free energy increases, so there is a driving force to form solid solutions from elemental powders. Finally, there is agreement between experimental and thermodynamic data confirming the formation of solid solutions.

Solubility data have been obtained at 20 °C. and 60 °C. for the following ternary systems:[Formula: see text]No evidence of the formation of double salts or of solid solutions in the first three systems was obtained. Ammonium sulphite monohydrate does not appear to dehydrate at 60 °C. in solutions saturated with sodium sulphite or ammonium chloride. In the study of the NaCl–NH4Cl–H2O system, the data agree with average values obtained from the literature and some discrepancies in the published data have been noted. In the NaCl–Na2SO3–H2O system some anomalous results can be explained on the basis of the existence of solid solutions of the hydrated and anhydrous forms of sodium sulphite and sodium sulphate.

Information on phase formation in complex physical-chemical systems is the basis for the synthesis of new phases and thus informational-logical basis for the developing of new polyfunctional materials. For the first time set of sulfate-containing ternary systems was studied using a complex of methods for physical and chemical analysis, such as differential thermal analysis (DTA), visual-polythermal analysis (VPA). The nature of solid solutions based on Na2SO4–CaSO4 was identified; the values of force fields were calculated by Goldschmidt’s formula. The influence of the third component (М2SO4 (М-Li,K,Rb,Cs,Tl(I)) on the behavior and disintegration of these solid solutions was determined.

Experimental Solubility

Correlations of solubility data previously measured on ternary systems containing peroxodisulphates of monovalent cations have been established using the method of relative activity coefficient expansion. The relationships obtained give a fairly good representation of experimental solubility curves for systems which do not form solid solutions. The general form of the correlation function is discussed in relation to the resultant ionic strength of saturated solution.
