“…43 Additionally, characteristics like coefficient of thermal expansion and thermal conductivity were substantially influenced by the evident differences in these properties and their impact on interface bonding during solidification of the molten cast. 44 The difference gets more pronounced as the concentrations of the reinforcement increases from 1% to 4% as seen in Fig. 8 and substantial increase in compressive strength was observed in both System-I and System-II.…”

The endeavour of this research work is to scrutinize the effect of the reinforcement materials silicon carbide (SiC) and graphite (Gr) on the mechanical properties of Al-Mg-Si alloy (AA-6061). Samples of the composites were fabricated using the stir casting technique, incorporating four weight (wt.) ratio of individual reinforcement and two different sizes of the particles. SiC, a resilient ceramic, and graphite were chosen as reinforcement to estimate their shared impact on the mechanical characteristics of the composite. Hybrid metal matrix composite (MMCs) were created with varying weight percentage of 4%, 3%, 2%, and 1% for the above selected reinforcements separately with two combinations of the particle dimensions: System-I (SiC-25 µm and Graphite- 75µm) and System-II (SiC-5 µm and Graphite- 25 µm). Mechanical characterization of composite samples including hardness, wear rate, compressive strength, was analyzed for both System-I and System-II. Scanning electron microscopy was employed for microstructure analysis, and X-ray diffraction was used for phase identifications. Mechanical characterization revealed both System-I & II with uniform dispersion of reinforcement particles. System-I exhibited higher density and lower wear resistance compared to System-II under all load conditions.

“…41 This possibility of mild agglomeration or clustering is generally seen to increase with an increase in reinforcement phase concentration. 42 Figures 8(c) and (d) indicate the microstructure of CZG003 and CZG004. As the concentration of reinforcement increases, the reinforcement particles in the micrographs also come nearer to each other thereby indicating the increase in amount of reinforcement.…”

The present study aims at investigating the properties of copper matrix-based hybrid metal matrix composites (MMCs) reinforced with ZrO2 and Graphite. The MMCs were prepared using stir casting technique. The composite material was developed for its application in thermal management structures. The properties of the prepared MMCs were found to be dependent on the reinforcements content present in the MMCs. ZrO2 and Graphite reinforcements were added (0.5–0.5, 1.0–1.0, 1.5–1.5 and 2.0–2.0 wt %) in the four composite samples prepared via stir casting. Amongst several available techniques, stir casting was chosen to prepare the samples due to its simplicity and economic viability. The phase identification was done by using X-ray diffraction (XRD) and the microstructure was observed using Scanning Electron Microscopy (SEM). No intermediate phase was observed from the XRD results. The reinforcement phase was found to be dispersed in a uniform manner as observed through the SEM micrographs. The density of the samples was found to decrease with an increase in the reinforcements content. The density of the composite sample containing 2 wt. % of each reinforcement was found to be 8.01 g/cm3 which was 10% lesser than pure copper. Hardness of pure copper sample was found to be 35.71 BHN; however, the hardness of composite sample containing 4 wt. % of each of the reinforcements was found to be 70.14 BHN which indicates an increase of around 100%. Wear rate of pure copper and composite sample containing 5 wt. % of each of the reinforcements was found to be 0.3788 mm3/Km and 0.3603 mm3/Km, respectively, at 20 N load. However, the composite samples consisting of 4 wt. % of each of the reinforcements exhibited wear rate of 0.3001 mm3/Km which was 20% lesser than that of pure copper at the same load. The compressive strength of composite sample containing 2.0 wt. % ZrO2 and graphite was found to be 674.57 MPa which was around 1.25% higher than the composite sample containing 0.5 wt. % reinforcements. The specific heat of the samples was found to increase marginally with an increase in reinforcement content. It is expected that the hybrid composites developed will be suitable for use in structural applications pertaining to thermal management.
