“…The properties of AlSiC MMCs are for better than Aluminium and steel. AlSiC MMC has minimum deflection, stress, strain and has good factor of safety as mentioned below [21]. As per previous literature various properties such as modulus of elasticity (E), density (ρ) and passions ratio (µ) are 1.4 * 10 6 (N/m 2 ), 2800 (Kg/m 3 ) and 0.14 respectively.…”

The objective of this paper is to find out the most favourable material and immensely fitted cross-section for TATA 11O9 TRUCK ladder chassis. This research aims to optimize the weight of the chassis. For this we have taken three materials like structural steel, carbon fiber and Aluminium silicon carbide metal matrix composite. The automotive chassis is the vehicle's base, providing strength and support to the numerous body sections such as suspension, engine, power train, and so on. Recent advancements in the realm of automobiles have expanded rapidly, particularly in the current context. Problem faced by modern days vehicle is the heavy weight. So here we try to decrease the weight of chassis frame by using various method and increase the strength, efficiency of chassis. Reducing the weight of chassis results in increase in performance of vehicle, reduce fuel consumption, less wear and tear of tire. The designing of the chassis is done on software SOLIDWORKS and further analysis is done on ANSYS19.2. The current chassis mass with traditional material is 1560 Kg which is made up of structural steel, whereas the chassis mass with Aluminium carbide metal matrix composite material is 523.45 Kg. According to the analysis, the chassis mass has been reduced by 66.44%, which would eventually hinder the vehicle's performance.

“…The findings explain that the fabricated hybrid composite showed 35% improved tensile strength and 40% enhanced hardness. Ashish Kumar et al [19] fabricated AA7075-Al 2 O 3 -coconut shell ash composites via a stir-casting route. The coefficient of thermal expansion of fabricated composites reduced with the inclusion of alumina and coconut shell ash, but the corrosion resistance increased gradually with the inclusion of reinforcement particles in the AA7075 base matrix.…”

The present work highlights the significant effects of varying wt% of Sn metal powder in the hypo eutectic Al-7Si/10 wt% Al2O3 composite. The composites were manufactured through a multi-stage stir casting route and characterized for mechanical and wear behavior using ASTM standards. The results revealed that the increase in Sn content up to 4 wt% in the matrix enhanced the microhardness, tensile properties, and reduced the porosity. The Al-7Si/10 wt% Al2O3 composite with 4% Sn particle reinforcement shows the highest tensile strength and hardness of 132 MPa and 90 BHN, respectively. All composites exhibited a ductile mode of failure, as evidenced by the tear ridges and dimples on the tensile fracture surface. By adding of Sn metal powder to the material system, the wear rate and coefficient of friction were reduced. At 1000 m of sliding distance and 1 ms−1 of sliding velocity, the wear loss of 8 wt% Sn composite was decreased by 88.8% as compared to Al-7Si base alloy at a normal load of 10 N whereas, at 40 N of normal load, the wear loss was decreased by 66.6%. During the wear process, the Sn metal powder surfaced and formed a thin tribo film that mechanically mixed with the surface, resulting in reduced friction. The layer at the interface prevented direct contact between asperities on the mating surface, which reduced wear loss. The composites without Sn metal powder exhibited adhesive wear and delamination as the primary wear mechanisms, while composites with Sn showed predominantly adhesive wear. Regression analysis followed by a desirability function approach was carried out to develop the model and optimize the operating conditions of the experiments.

“…Composites commonly have a fiber or particle section this is stiffer and more potent than the non-stop matrix section and function the essential load wearing members. The matrix acts as a load switch medium among fibers, and in much fewer best instances in which the hundreds are complex, the matrix can also additionally even need to undergo hundreds transverse to the fiber axis [14][15][16][17][18][19][20]. The matrix is greater ductile than the fibers and hence acts as a supply of composite toughness.…”

Researchers and various industries place a high value on metal matrix composites (MMCs) made using friction stir processing (FSP), which has superior and finer particle dispersion and also successfully displays equalized grains through dynamic recrystallization. In the present research work magnesium alloy AZ31 reinforced with MoS2 was successfully made using FSP. The FSP samples are fabricated at 1000, 1200 and 1400 RPM while the traverse speed of 70mm/min is kept constants for all the FSP samples. AZ31 has light weight and excellent weight to strength ratio for this reason it can be used in various application like Aerospace Industry, Ship building and automotive applications but it has limitation in wear resistance and AZ31 Alloy is reactive and can corrode easily in corrosive medium. The present work aim is to investigate the mechanical and tribological behavior of AZ31/MoS2 Metal Matrix Composite (MMC) and then compared the properties with the base alloy. Here the specimen AZ31 is reinforced with MoS2 and processed by FSP to improve the tribological behavior the pin on disk wear test is conducted to study the wear performance. To investigate the hardness of the specimen, the hardness test is performed on the Brinell hardness apparatus. The corrosion behavior of MMC is also investigated by the immersion test conducted with 3.5% weight NaCl solution for 24 hours. All these properties are then compared with base Alloy. The SEM analysis is also investigated to study the surface behavior.
