Abstract

The phonon dispersion relations of Nb–Ta and Pd–Pt alloy systems are calculated in the framework of the coherent potential approximation. Though only a few experimental data are available to be compared with the theory, the satisfactory agreement obtained, indicates the necessity of further experimental and theoretical effort in the study of alloy phonon dispersion relations. Die Phononendispersion–Beziehungen von Nb–Ta- und Pd–Pt-Legierungen werden im Rahmen der CPA berechnet. Obwohl derzeit nur wenige experimentelle Daten zum Vergleich mit der Theorie zur Verfügung stehen, zeigt die zufriedenstellende Übereinstimmung die Notwendigkeit weiterer experimenteller und theoretischer Untersuchungen der Phononendispersion.
