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).

“…Fabrication was carried out by considering all the stir casting parameters constant. The results reveals that the mechanical properties and the tribological properties were increased by the addition of micro SiC particles [14]. Prabaharan et al, examined the characteristics of aluminium matrix composite when reinforced with SiC in different weight percentage using stir casting.…”

Stir casting plays a major role in production of Al-SiC10% composites for aero space and automobile applications. However, obtaining the composites with homogenous distribution of the SiC particles, low porosity and without clustering of reinforcement particles were still a major problem faced by the research community. These kinds of casting defects were overcome by the Additive Manufacturing (AM) technology. In this research, AlSi10Mg parts were manufactured by Laser-Powder Bed Fusion (LPBF) method, one of the AM techniques. The mechanical and morphological characteristics of AM samples were compared with the Stir Casted (SC) samples. The in uence of print orientation on the mechanical properties was also evaluated. It was found that the AM samples printed along the XY directions shows 26.5% and 8.2%higher fracture toughness and shear strength than AM samples printed along the Z directions. Both AM and SC samples were analyzed for the porosity% using the Optical Microscope (OM).The result shows that the AM sample shows reduced porosity of 1.4%. Mechanical testing such as tensile test, hardness test, fracture toughness test and double shear stress were carried out. The results obtained from the tensile test AM samples show 14.6% higher tensile strength than the SC samples, from the hardness test AM samples show 18.6% higher hardness strength than the SC samples, from the fracture toughness test AM samples show 33.4% higher fracture toughness strength than the SC samples and from the double shear stress test prove that the AM samples show 24.6% higher shear stress than the SC samples. The outcome of this research, it was proved that additive manufactured AlSi10Mgsample shows enhanced mechanical and morphological properties when compared with the conventional stir casting process.

“…They discussed the hardness, tensile strength increases and the wear resistance also increases after adding y ash and B 4 C content. Dipankar et al [23] It is evident from the above literature, very few researchers had worked on the reinforcements of y ash and SiC mixed with Al 7075. The mechanical and tribological properties of y ash and SiC reinforcements are very minimal.…”

In the present research work an effort has been made to study the wear and frictional behavior of Aluminium Metal Matrix composite (Al 7075 as a base alloy and fly ash (FA) and silicon carbide (SiC) as reinforcements) by using the stir casting method. To carry out this work, the wt. % of reinforcements FA (2.5%, 5%, 7.5% and 10%) and SiC (2.5%, 5%, 7.5% and 10%)have been used 5%, 10%, 15% and 20%. Initially, the mechanical studies have been conducted and the best mechanical properties obtained at 20 wt. % of FA and SiC. Later on, the composite was fabricated by 20 wt. % of FA, SiC reinforcements are used to check the wear and frictional behavior on a pin-on-disc machine at the dry condition. The dry sliding wear behavior was carried out at various input parameters such as applied force (10N, 20N, and 30N), sliding velocity (1.5m/s, 3m/s, and 4.5m/s), and sliding distance (1000 m, 2000 m, and 3000 m). Further, a scanning electron microscope (SEM) are used to observe the mixing of reinforcements and examine the worn surfaces. A response surface methodology (RSM) is the reasonable and accurate method for conducting the experiments and identifying the optimal wear parameters. Moreover, the RSM was helped to identify the most significant factor, which was the influence on the wear rate. Finally, it is decided that the applying force is the utmost significant factor that leaves an effect on wear rate. The sliding velocity and distance are acting as the lesser influence on the performance indicator.
