摘要：

Rapid solidification is one of possible method to produce nanocrystalline alloys. In case of aluminium based rapidly solidified alloys, the material is formed of fcc-Al grains and intermetallic phases crystalline ether quasicrystalline. The study of these intermetallic phases is complicated by strong signal of fcc-Al in almost all analytical methods. It this paper, the study of whole ribbons prepared by melt spinning and study of extracted phases will be compared. The advantages and disadvantages of both sample types will be described. Both type of samples were studied by X-ray diffraction and scanning and transmission electron microscopy. More over the ribbons were studied by positron annihilation spectroscopy
