Abstract
The technique of powder consolidation under a high quasi-hydrostatic pressure was used for consolidating quasicrystalline AlCuFe powders manufactured by water-atomization technique. The optimum conditions for the consolidation were selected through the analysis of the dependence of sample porosity on pressure and temperature in various stages of the consolidation process. The consolidation process took 2–3 min. X-ray investigation of sintered samples was performed, their hardness was measured. A softening of samples with the growth of pressure was revealed, which was interpreted as the influence of phason defects created by deformation while consolidation.
