Abstract
In the rigid band approximation the electronic structure of W–Re and Mo–Re alloys is calculated and their band contribution to the elastic moduli Cik. Critical Re concentrations are determined at which electronic topological transitions occur. An analysis of the computational results for Cik is invoked to discuss variations in the degree of “covalency” and “metallicity” of the chemical bonds in rhenium-doped tungsten. Consideration is given to the role of the elastic anisotropy constant of W–Re and Mo–Re alloys and to its effect on the individual dislocation mobility and plastic properties of these alloys.
In der Naherung starrer Bander wird die elektronische Struktur von W–Re- und Mo–Re-Legierungen und ihr Bandbeitrag zum Elastizitatsmodul Cik, berechnet. Kritische Re-Konzentrationen werden bestimmt, bei denen topologische elektronische Ubergange auftreten. Eine Analyse der Computerer- gebnisse fur Cik wird eingeschlossen, um Anderungen im Grad der „Kovalenz” und „Metallizitat” chemischer Bindungen in Rhenium-dotiertem Wolfram zu diskutieren. Berucksichtigt werden die Rolle der Konstante der elastischen Anisotropie von W–Re- und Mo–Re-Legierungen und ihr Einflus auf die individuelle Versetzungsbeweglichkeit und plastischen Eigenschaften dieser Legierungen.
