“…Due to its low intensity, the amorphous halo associated with the FMG particles is difficult to find when located next to crystalline peaks. According to a previous study, 17 the halo is located at around 44° 2θ diffraction angle. Therefore, the XRD patterns taken by HAM73 were magnified and shown in Figure 2.…”

“…Details of the preparation method can be found in our previous work. 17 Different SiC and FMG levels were blended with aluminum powder in a low-energy horizontal blender at a rotational speed of 100 r/min for 2 h. The samples were prepared by the high-energy planetary ball mill. The compositions of the samples and their respective codes are shown in Table 1.…”

In this investigation, hybrid aluminum matrix composites reinforced with Fe-based metallic glass (FMG) and SiC particles were synthesized using spark plasma sintering (SPS) at different sintering temperatures. The effects of sintering temperature on densification, phases, microstructure, and mechanical properties of the composites were evaluated. The findings indicate that the density of the sintered samples improved with increasing the sintering temperature. The X-ray diffraction results showed no remarkable difference in the phases of the samples sintered at different temperatures; only some small structural changes occurred in the metallic glass reinforcements. The sintering temperature had a significant effect on mechanical properties. For example, the hybrid aluminum matrix composite reinforced with 3 vol% FMG and 7 vol% SiC sintered at 550°C exhibited the ultimate compressive strength of 494 MPa, which is about 47% higher than the same composite sintered at 450°C.

Recently, the demands of composite materials used in various engineering applications are growing higher because of their outstanding mechanical and thermal properties. This study represents an experimental investigation to determine mechanical properties of Al-based composites materials using Cu and SiC as reinforcement. Al-30-wt%-Cu, Al-40-wt%-Cu, Al-30-wt%-SiC, and Al-40-wt%-SiC composite bars were fabricated using stir casting process to ensure uniform distribution of reinforced elements. The composite bars were prepared into required shape to conduct test for evaluating mechanical properties. Al-40-wt%-Cu shows improved properties such as, hardness, strength, and impact energy absorption than Al-30-wt%-Cu due to more presence of Cu content. Al-30-wt%-Cu and Al-40-wt%-Cu bars showed improved mechanical properties than both Al-30-wt%-SiC and Al-40-wt%-SiC. It is also seen that Al-30-wt%-Cu and Al-40-wt%-Cu showed high hardness, yield strength, and impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. On the other hand, Al-30-wt%-Cu is 3.5% lightweight than Al-30-wt%-SiC and Al-40-wt%-Cu is 2.11% lightweight than Al-40-wt%-SiC. Al-30-wt%-Cu and Al-40-wt%-Cu showed improved specific hardness, specific yield strength, and specific impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. In addition, Al-40-wt%-Cu showed better mechanical properties among the bars.

This study investigates the combined influence of Si element and reinforcing particles on the hardness and wear performance of aluminum matrix composites. The composites in focus include Fe‐based metallic glass (FMG) monolithic reinforced and FMG/SiC hybrid reinforced Al‐5 wt% Si matrix composites, fabricated through spark plasma sintering (SPS). A comprehensive investigation was carried out, encompassing the analysis of microstructural attributes and the examination of worn surfaces through field emission scanning electron microscopy. Additionally, the study scrutinized two pivotal factors—hardness and density—recognizing their pivotal roles in determining the tribological performance of these composites. The experimental findings demonstrated the presence of an oxide protective layer on the worn surfaces of all specimens. Although, FMG/SiC hybrid reinforced Al‐5 wt% Si matrix composite possessed the highest hardness value, the best tribological performance was observed in Si‐bearing monolithic reinforced composite. The addition of Si to the matrix of monolithic reinforced composite facilitated improved densification behavior and enhanced the distribution of reinforcing particles, resulting in a more stable and protective oxide layer in this specific sample. Furthermore, the study identified a transition in the operative wear mechanisms from delamination to mild abrasion and adhesion with the inclusion of Si element.This article is protected by copyright.
