dc.description.abstractenA brief outline of the processing parameters involved in the search for technique offering efficient consolidation of high-temperature strength Al-based powdered alloys reinforced by metastable nanoquasicrystalline particles is presented. Feedstock powder of Al94Fe3Cr3 alloy was employed in experiments. Superior advantages of the coldspraying as alternative solid-state process for consolidation and structural performance of quasicrystalline alloys by plastic deformation is discussed in comparison with that resulted from currently employed hot extrusion put into practice at the 623 K. As opposed to extrusion assisted by unidirectional deformation, adiabatic shear instability is primary responsible for creating the mostly effective intimate metallic bonding between the adjacent Al-powder particles under cold spraying when the temperature was even well below melting point, i.e. 473 K. The main benefit of cold-spraying is that the composite quasicrystalline structure in the interior of heavily deformed particles was believed to be actually the same as that of feedstock powder while warm extrusion results in the decrease by 23% fraction volume of metastable quasicrystalline particles, shifting their decomposition to the lower temperatures. Advantage of cold-sprayed Al94Fe3Cr3 alloy concerns excellent balance between high ductility (plasticity characteristic δH ≈ 0.9) and high strength that superior roughly about 35% to that of as-extruded composite.uk
