Electronic Structure of Al-Li Alloys by Means of Electron Microprobe

Abstract

By means of an electron microprobe the lithium-K-and aluminium-K-X-ray emission lines of Al-Li alloys were studied. The Li-line can be well described by the calculated emission line. The evaluation yields the transfer of electrons from the Li-s- to the Al-p-band during alloying. The charge transfer is enhanced by heat treatment. The dependence of the elastic modulus on the charge transfer is discussed.
