Abstract

The structure and properties of Al–Fe–Cu and Al–Fe–Cu–Sc quasicrystal alloys have been investigated applying the methods of metallography, X-Ray analysis, transmission and focused-beam electron microscopy, differential thermal analysis (DTA), and electrical resistivity method. The cast and ion-plasmous sprayed alloys or composites having Al (industrial), Al–6Mg, Al–7Si, and Al–5Cu binders strengthened with Al65Cu20Fe15 filler have been studied. The Al–Cu–Fe and Al–Cu–Fe–Sc have been assumed to show promise as advanced resistance alloys. Macroheterogeneous composites strengthened with the quasicrystal filler can be obtained by furnace infiltration that ensures strong adhesion of structural constituents.
