摘要：
Quasicrystalline and crystalline phase transitions from amorphous thin films of the Al-Co-Cr-Fe-O and Al-Mn-Si-O systems have been studied in the case of in-situ heating treatment in the transmission electron microscope. Heating the films up to 800 degreesC, grains with quasicrystalline decagonal phase as structure were developed in both systems. The structural and chemical analysis indicates that, in both cases, the decagonal phase is an oxygen-containing quasicrystalline phase. (C) 2000 Elsevier Science B.V. All rights reserved.
