Zusammenfassung

Die Mischungslücke in den Systemen: TiC−{ZrC, HfC} und VC-{NbC, TaC} wird im Bereich von 1200° C bis zur Temperatur des kritischen Punktes experimentell ermittelt und mit Hilfe der freien Exzeß-Enthalpie von der Form: ΔG E=x(1−x) {(a 0+a 1 T)+(2x−1)(b 0+b 1 T)} berechnet.

Abstract

The miscibility gap within the systems: TiC−{ZrC, HfC} and VC—{NbC, TaC} has been experimentally determined in the region from 1200°C up to the temperature of the critical point. A calculation of the binodal curve has been carried out by means of an excess free enthalpy of the form: ΔG E=x(1−x){(a 0+a 1 T)+(2x−1)(b 0+b 1 T)}.
