Zur Berechnung der thermodynamischen Daten eines tern�ren Systems aus den zugeh�rigen bin�ren Systemen

Solidus and liquidus temperatures in the uranium-plutonium-zirconium system

“…Excess Gibbs energies in the ternary liquid and solid phases were calculated from the values for the three binary systems by means of the "Kobler interpolation equations" (27) G E = (1 -X Pu ) 2 Gg /Zr + (1 -Xu) 2 Gf r/Pu + (l -X Zr ) 2 G u/Pu [10] in which G E at a ternary composition point is calculated from the values G|j, Zr results should be discounted. Nevertheless, the general shape of the reported isotherms is the same as that of the calculated isotherms.…”

Thermodynamic calculations in the Cu-In-Sn system

“…In this paper, the thermodynamic properties for the ternary Cu-In-Sn system are calculated for the sections with constant molar ratio In:Cu=1:1, 1:4, 4:1 and 9:1 at 873K up to 1673 K and by different models Kohler [10] [11].…”

“…There are usually two kinds of models which are popular for description of ternary systems. These are geometrical models symmetric [10] and asymmetric [11] models.…”

Density Of The Copper-Rich Cu-Pb-Fe Alloys

“…In the case of non-ideal mixture, molar volume can be expressed by the relation: (13) where: The excess of molar volume mixture can be described in a way analogous to the excess molar free energy of ternary solution with use of models [10][11][12][13][14][15][16]. If ternary and all three binary solutions, which can be formed with ternary mixture components were regular, Toop's model [10] would describe its thermodynamic properties rigorously.…”
