Summary

In recent years, quasicrystalline (QC) phases, due to complex of unusual properties, have attracted much attention as promising base for new materials. At present various kinds of techniques are considered for QC production [1–4]. A number of papers report that QC phases can be produced by mechanical alloying (MA) of elemental components or by subsequent annealing of MA powders [5, 6].

This paper, in continuation of the previous research on Al-Cu-Fe QC preparation by MA technique [11–14] and investigation of possibility to obtain bulk materials by precursor powder compaction [14], presents the first results on obtaining the Al-based composite materials reinforced by the Al-Cu-Fe QC phase. As the final product of the MA technique is powder, the bulk material can be obtained by low temperature consolidation with subsequent annealing or by hot consolidation. The higher the temperature of thermal treatment of bulk specimens, the better sintering of powder particles and higher the mechanical properties. However, the Al-Cu-Fe QC phase can dissolve in aluminium matrix at annealing with failure of useful properties. This is the point of special interest of present investigation.
