Abstract

It was demonstrated that vapour-deposited thin film systems of aluminium and iron are very suitable for studying the formation of different intermetallic phases. Morphology, crystallography and composition of the phases developed as a result of heat treatments were analysed by electron microscopic techniques. F.c.c. aluminium and b.c.c. iron were present in the as-deposited films prepared by sequential deposition of the constituents at room temperature. During heat treatment of multilayer systems the icosahedral phase developed first above 250°C, simultaneously with metastable Al6Fe. In AlFe bilayer systems Al6Fe started to develop above 250°C; no icosahedral phase was detected by selected area electron diffraction. Above 500°C, mainly the stable η-Al5Fe2 was observed in bilayer systems, while Θ-Al3Fe formed in multilayer samples. At a substrate temperature of 300°C, the icosahedral phase developed directly by sequential deposition of aluminium and iron.
