Gibbs-Duhem integration techniques

While the main driving force in [43, 44] was to avoid direct particle transfers, Escobedo and de Pablo [38] designed a pseudo-NPT method to avoid direct volume fluctuations which may be inefficient for polymeric systems, especially on lattices. Escobedo [45] extended the concept for bubble-point and dew-point calculations in a pseudo-Gibbs method and proposed extensions of the Gibbs-Duhem integration techniques for tracing coexistence lines in multicomponent systems [46]. [Pg.361]

The partial pressures of Cu in the system Cu-Fe-Pt in the temperature range 1240 to 1360°C have been measured by the Knudsen effusion technique and the thermodynamic properties of this system at 1300°C have been derived [1989Par]. The activities of Fe in solid solutions at 1300°C were calculated by Gibbs-Duhem integration of the Cu activities. The experimental alloys were prepared from Cu (99.999 mass%), Fe (99.999 mass%) and Pt (99.99 mass%) by induction melting in an alumina cmcible under an Ar atmosphere. The alloy buttons were then homogenized in a H2 atmosphere for 5 to 30 days at 900 to 1300°C. [Pg.574]
