In this research, aluminium metal matrix composites (AMMCs) have been manufactured through friction stir processing (FSP) by reinforcing micro sized SiC particles in an Al6061-T6 alloy. The consequences of the volume percentage of reinforced SiC particles on mechanical properties and microstructural features were analyzed for the developed AMMCs. Microstructural evaluation of a cross-section of a friction stir processed (FSPed) sample has been conducted through Electron backscatter diffraction (EBSD) Energy dispersive spectroscopy (EDS) and a scanning electron microscope (SEM) technique. Microhardness tests were conducted athwart the cross section of FSPed specimen to obtain microhardness feature. A tensile test of FSPed samples has been conducted on a universal testing machine (UTM). Homogeneous distributions of SiC particles were found in the stir zone without any consolidation of particles. The size of the reinforcement particles was decreased slightly by increasing the volume fraction. It has been found that increasing the volume fraction of SiC particles, enhance the tensile strength and microhardness, but decreases the ductility of the aluminium. The maximum ultimate tensile strength (UTS) and microhardness were obtained as 390 MPa and 150.71 HV, respectively, at 12% volume percentage of reinforcement particles. UTS and microhardness of the FSPed Al/SiC have been improved by 38.29% and 59.48% respectively as compared to Al6061-T6. The brittle nature of the FSPed Al/SiC has increased due to a rise in the volume fraction of micro sized SiC particles, which causes a decrease in ductility.

Friction stir processing (FSP), as an advanced technique, was employed to fabricate in situ aluminum composites with the aim to elucidate the correlation between microstructure and mechanical properties of the obtained composites. The novelty of the work is to utilize simultaneous incorporation of Fe and Cu powders into the friction stir zone in order to fabricate in situ aluminum composites. To achieve the goal, the loading content of Cu and Fe powders and the process pass number (1 pass to 5 passes) were altered. While the total loading content of Fe and Cu powders was kept constant, the weight percentages of these reinforcements were varied (25%, 50%, and 75%). Microstructural characteristics were examined using scanning electron microscopy and optical microscopy. Five passes FSP resulted in smaller grain sizes of the Al matrix, smaller and less agglomeration of the reinforcements as well as homogeneous dispersion of the reinforcement features and thus, enhancement of the mechanical properties of the composites. X-ray analysis and energy dispersive spectroscopy confirmed in situ formation of Fe-Al and Al-Cu intermetallic compounds in the composites. The tensile testing outcomes proposed the 50wt% Fe-50wt% Cu/Al composite fabricated in 5 passes as the optimum formulation achieved in this research. This can be attributed to the smaller grain size of the matrix in the friction stirred zone and more homogeneous dispersion of the reinforcements in the matrix. Furthermore, this strengthening was affected from the presence of more amounts of well dispersed intermetallic compounds in situ formed during 5 passes. The average tensile strength (207 MPa) and hardness (73 Vickers) of the composite were approximately 175% and 160% greater than that of the unreinforced aluminum (75 MPa, 28 Vickers), respectively. Increasing the process pass number from 3 to 5 passes not only had strengthening and hardening effects but also improved the composite elongation at break.
