Phenomenological Calculation of L1 sub 0 -Disorder Transition Temperature in a Gold--Palladium System
A phenomenological calculation based on the tetrahedron approximation of the cluster variation method with a Lennard--Jones type energy expression was performed to calculate the transition temperature of L1 sub 0 -disorder phases in an Au--Pd system. The transition temperatures are placed between 30...

| Zusammenfassung: | A phenomenological calculation based on the tetrahedron approximation of the cluster variation method with a Lennard--Jones type energy expression was performed to calculate the transition temperature of L1 sub 0 -disorder phases in an Au--Pd system. The transition temperatures are placed between 300-350K depending upon the two kinds of Lennard--Jones parameters employed. The origin of the discrepancy between the present calculation and experimental phase diagrams is discused. 15 ref.--AA |
