Aluminum based hybrid metal matrix composite with more than two particle reinforcement is very much popular for heavy duty application. In the present study, mechanical properties of AA6061 based hybrid composite synthesized using liquid metallurgy route with 6 wt. % total reinforcement (B4C+SiC) with different proportions of B4C wt. % and SiC wt. % were investigated. Hardness measurement and uniaxial loading techniques were used to characterize the mechanical properties of the as-cast hybrid composites. The improvement in mechanical properties, such as Vickers hardness value, UTS, yield strength and elongation were tried to explain using various hypothesis proposed by previous studies.The role of clustering theory and effect of binary eutectic Mg2Si phase have played a key role in defining the mechanical properties of the hybrid composites. Addition of Alkaline Earth Metal (Mg) during the synthesis process have led to the exploration of some interesting results from the uniaxial tensile loading tests.

“…AA6061/B 4 C/SiC hybrid composites increase in hardness while increasing with the weight percentage of SiC reinforcement on AA6061 alloys. Almost all research demonstrated that the addition of B 4 C to Al matrix-based composite materials increased their hardness [2][2] [4]. study of uctuating microhardness may be the result of improper particle interactions [2] [3].…”

This research explains the Mechanical properties of Aluminium 6061 alloy and hybrid metal matrix B4C/ZrO2/SiC composites which is prepared by stir casting method. In this research B4C has 2%composition, ZrO2 was 2%,4% and 6% and SiC was 4%, 8% and 12% composition. The hybrid metal matrix composites are conducted hardness, impact, flexural strength, compressive strength, Tensile strength and Tensile fracture surface. These investigations study the effect of reinforcement on hardness, tensile, compression, impact and flexural strength. The effect of reinforcement study reveals that the pure Aluminium 6061 alloy shows poor results compared to Hybrid composites. The results confirmed that increasing in SiC percentage given high tensile strength, impact and hardness of the material. Adding SiC was given high quality mechanical properties. Adding 2% B4C to Al6061 reduces the impact strength of the material. Reinforcement of ZrO2 reveals improvement of mechanical properties. Additionally, this research studies the elongation, yield strength and behaviour between load and displacement of composite materials.

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).
