Abstract
Samples of an Al-Fe alloy of composition of (2.15±0.08) mass %, admixtures of not more than 0.2 mass %, were studied. It was demonstrated by XPA that the intermetallide of composition Al3.2Fe and polycrystalline aluminium were formed at alloying of metals. The interaction of Al-Fe alloy samples with liquid Ga-In eutectics was studied by methods of scanning electron microscopy and energy-dispersive X-ray spectroscopy. It was found that an Al-Fe alloy became activated slower by liquid Ga-In eutectics than polycrystalline aluminium and Al-Ni alloys. The intermetallide phase of Al3.2Fe composition does not undergo significant chemical changes. It was demonstrated by multiple frustrated total internal reflection IR spectroscopy that aluminium chloride complexes of various compositions were in situ formed during the interaction of activated samples of an Al-Fe alloy with tert-butyl chloride. The complexes showed catalytic properties.
