STUDIES ON APERIODIC CRYSTALS IN Al-Mn AND Al-V ALLOYS BY MEANS OF TRANSMISSION ELECTRON MICROSCOPY

Abstract
Electron microscopy has been used to study quasicrystals and T phase in rapidly cooled Al-14at%Mn and Al-16at%V. The T phase can also be produced by interdiffusion in evaporated Al/Mn layers. Also in these experiments we have observed a new crystalline phase with structural elements related to the aperiodic crystals by a shear parallel to a particular symmetry direction. The phase transitions between the quasicrystalline or the T phase to the crystalline or amorphous phases were studied in situ in a high-voltage electron microscope
