Lightweight materials are extremely needed for the manufacturing of industrial parts and are used in aerospace, automobile body shops, biomedical instruments, etc. Aluminium alloy is one of the light-weight materials, and it fulfills the industrial demands based on their natural strength/stiffness, enhanced temperature permanence, superior wear, and corrosion resistance. This experimental work considered aluminium alloy (AA8014) with reinforced particles of silicon nitride (Si3N4) and zirconium dioxide (ZrO2) for preparing aluminium hybrid composites. Hybrid composites are prepared by a stir casting process involving different process parameters. L27 orthogonal array is used for optimizing the stir casting parameters with the assistance of the statistical Taguchi approach. Stir casting parameters are the percentage of reinforcement (4%, 6%, and 8%), stir speed (400 rpm, 500 rpm, and 600 rpm), stir time (20 min, 25 min, and 30 min), and molten temperature (700 oC, 800 oC, and 900 oC). Mechanical performance such as wear and microhardness of the hybrid composites is evaluated. Minimum wear and higher microhardness are encountered at a percentage of reinforcement = 6%, stir speed = 400 rpm, stir time = 30 min, and molten temperature = 900°C. In wear analysis, the percentage of reinforcement highly influences the wear properties (7.06% contribution). In microhardness analysis, molten temperature parameter is the extreme influencer (11.15% contribution).

“…Aluminium Hybrid Matrix composites encompass Aluminium metal matrix composites with two or more reinforcements. Hybrid refers to the higher number of reinforced materials in varying or constant proportions [3]. The hybrid phase is fabricated to achieve augmented mechanical properties and/or thermal properties that were previously impossible with single reinforcement [4][5][6][7].…”

Hybrid Metal Matrix composites have emerged as an epicentre of material research due to their vast applications and a wide array of reinforcement combinations. In this experiment, a hybrid Aluminum metal matrix composite has been fabricated by the double (two steps) stir casting method. The present study evaluates the mechanical properties of AA6061 in varying concentrations of silicon carbide with 5, 10, 15 and 20 weight percent (wt.%), in addition to Rice Husk Ash, Tungsten Carbide and Alumina Powder which are in a fixed quantity. Mechanical properties have been evaluated by conducting an Impact test, Hardness test, Flexural test and Tensile Strength. In addition, micrograph Images have been incorporated for analysing the microstructural characteristics of the Hybrid AMMC. It was observed that MMC properties such as Tensile Strength, Yield Strength, Hardness, Impact Strength were highest at 20 wt.% SiC. Hence, it was inferred that 20wt% SiC was an appropriate concentration for applications in automobile and aerospace pertaining to its augmented mechanical properties. In conclusion, prospects of future research are also explored.

Objective: To develop and evaluate the mechanical behavior of 3, 6, 9 and 12 wt. % of B 4 C reinforced Al6061 alloy composites. Method: These composites were produced by utilizing stir cast process. The prepared metal composites were characterized by SEM, EDS and XRD analysis to know the distribution of particles as well as presence of particles in the Al6061 alloy. Various mechanical properties were evaluated as per ASTM standards to know the impact of boron carbide particles on the properties of metal composites. Findings: By adding B 4 C particles the hardness, ultimate tensile, yield strength and compression strength of the Al6061 alloy matrix was enhanced 23.9%, 15.4 14.9% and 34.7% respectively. Further, there was slight decrease in the percentage elongation of B 4 C reinforced composites. Novelty: In the present research Al6061 alloy with 3 to 12 wt. % of B 4 C composites were synthesized by novel stir casting method called as two stage reinforcement addition process. In this process 80 micron sized boron carbide particles added in two stages into the molten Al6061 alloy to improve the wettability between the matrix and reinforcement particles.
