“…ere has been no study done on AA6082 to make hybrid composites employing (SiC + B 4 C) as reinforcement. Aluminum and silicon carbide (SiC) particles are chemically compatible and create strong bonds in the matrix [13]. ere are a number of advantages to using SiC as a reinforcement in AMCs because of its outstanding workability, easy machining, and inexpensive cost.…”

The microstructure and mechanical properties of an MMC based on AA 7075 and strengthened through silicon carbide (SiC) as well as boron carbide (B4C) elements were studied. The (SiC + B4C) combination was used in various weight percentages of 4, 8, 12, and 16% to create the hybrid composites utilizing the traditional stir casting procedure. XRD and SEM measurements were used to investigate the dispersion of the reinforced particles. For example, microhardness, impact strength, and ultimate tensile strength were measured on hybrid composites at room temperature. The density and porosity of the materials were also studied. The researchers found that increasing the weight percentage of the (SiC + B4C) mixture resulted in a small drop in % elongation. However, hybrid composites comprising 16% (SiC + B4C) weight reduction showed some decrease in hardness and tensile strength. Equated to unreinforced alloys, the hardness and tensile strength of hybrid composites rise by 8% and 21%, respectively. Reinforcement also resulted in a decrease in impact strength and density, as well as an increase in porosity.

This work presents the design and fabrication of a simple device for manufacturing metal foams and composites using infiltration. The particularities of the operation of this device are also included here, detailing examples of materials manufactured using it. This device was thought to produce composites and foams using matrices from low to medium melting points (e.g., from Mg to Cu alloys), limited to ~1200 °C. It can be used to produce samples large enough for their study and characterization, being cheaper than other devices reported in literature. Foams and composites of different sizes can be manufactured depending on the dimensions of the device, which can be modified according to the necessities. As examples, cylindrical (10 cm height and 5 cm in diameter) samples were manufactured infiltrating Al and Cu alloys on NaCl, NaCl-Al2O3 spheres mixture, and iron hollow spheres, for manufacturing respectively conventional, composite and syntactic foams. These materials were analyzed through Optical and Scanning Electron Microscopies (OM and SEM, respectively), and compression tests. Their densities and porosities were also measured. The analysis of the obtained materials revealed that following the correct experimental conditions, composites and foams without defects can be manufactured using this device. Different porosity and reinforcement percentages were obtained under these conditions, with the expected mechanical behaviors of such materials.
