The aim of this investigation was to comparison of microstructure changes of SiC reinforcing particles after plastic deformation process, in the cast composite F3K.10S. Aluminum matrix reinforced with 10 % vol. SiC particles was modified using friction stir processing method. Changing of distribution of the reinforcement particles was calculated and analyzed using new Mityushev’s RVE theory with Eisenstein-Rayleigh sums (M-sum) and PointSel software. The mechanical properties were determined on the hardness tests. The significant changes in the concentration, distribution and size of SiC particles were observed. Hardness testing of selected modified areas showed significant differences in the HV01 value in thermomechanical hardening areas. The resulting increase in hardness exceeded 30 %, but the obtained values of standard deviation have indicated that, despite a homogenized distribution of the reinforcing particles and their fragmentation, significant variations between individual measurements still persisted in the modified material. The processed material shows a considerable decrease in the average size of the reinforcing particles, i.e. from the initial area of 60÷70 square microns to a value below 20 square microns. It is believed that the obtained results should contribute to process optimization and a better understanding of the phenomena that occur during FSP modification.

Celem badań było porównanie zmian mikrostruktury cząstek wzmacniających SiC po procesie deformacji plastycznej odlewanego kompozytu F3K.10S. Kompozyt o osnowie aluminiowej wzmocnionej 10 % obj. cząstek SiC został zmodyfikowany metodą FSP. Zmianę rozkładu cząstek wzmacniających obliczono i analizowano za pomocą nowej teorii RVE Mityusheva z pomocą sum Eisenstein-Rayleigha (M-sum) i oprogramowania PointSel. Właściwości mechaniczne zostały określone na podstawie testów twardości. Obserwowano istotne zmiany w koncentracji, dystrybucji i wielkości cząstek fazy wzmacniającej SiC. Badania twardości wybranych, zmodyfikowanych obszarów wykazały istotne różnice w wartości HV01 w strefie termo-mechanicznego umocnienia. Obserwowany wzrost liczby twardości przekraczał 30 %, ale uzyskane wartości odchylenia standardowego pokazują, że pomimo poprawy dystrybucji cząstek wzmacniających i ich rozdrobnienia w zmodyfikowanym materiale nadal występują istotne różnice pomiędzy poszczególnymi pomiarami. Proces modyfikacji materiału wpływa na istotne zmniejszenie średniej wielkości cząstek wzmacniających, od początkowej powierzchni 60÷70 mikrometrów kwadratowych, do wartości poniżej 20 mikrometrów kwadratowych. Uzyskane wyniki powinny przyczynić się do optymalizacji procesu i lepszego zrozumienia zjawisk zachodzących podczas modyfikacji kompozytów metodą FSP.
