The agglomerates of master composite obtained by mechanical alloying were subjected to hot plastic consolidation to transform the powder into a solid material, and thus formed compacts were heated to a temperature of 350-400°C and extruded by KOBO® method. The obtained cylindrical samples were analyzed by computed tomography, which revealed a satisfactory level of the distribution of the reinforcing phase at a 25 wt.% fly ash concentration, and absence of the areas characterized by too high concentration of ceramic particles, which may act as a source of the adverse phenomenon of agglomeration. An improvement in the mechanical properties of composite samples was achieved compared with the sole matrix material. Keywords: fly ash, ALFA® composites, KOBO® method, ![]() |
