“…Silicon carbide, alumina, titanium carbide, boron carbide, and graphite particles are the popular reinforcement materials for these composites while the most common matrix materials are titanium, aluminum, and magnesium. In the past three decades, aluminum matrix composites (AMMCs) have received particular attention amongst MMCs due to their stiffness, high specific strength and superior wear resistance [3].…”

The effects of dual particulates addition on the mechanical behaviour of ADC12 alloy composites were studied. Boron carbide (B4C) and rice husk ash (RHA) particulates were used as the reinforcements in the ADC12 alloy base matrix. Hybrid composites were prepared by using liquid melt method, keeping 5 wt. % of B4C reinforcement constant and varying rice husk ash particles in steps of 3 and 6 wt. % in the ADC12 alloy. Samples were tested for microstructural characterization by using SEM and EDS. Mechanical behaviour like hardness, ultimate tensile strength; yield strength, percentage elongation and compression strength were evaluated as per ASTM standards. SEM photographs revealed the uniform distribution of B4C and RHA particulates in the ADC12 alloy and these particles were confirmed by EDS analysis. Further, hardness, tensile and compression properties of base matrix ADC12 alloy was enhanced with the addition of B4C and RHA particulates. Ductility of ADC12 alloy decreased after the incorporation of B4C and RHA particles.

The present work aims to enhance the mechanical performance of monolithic Al alloy and single reinforced metal matrix composite using a hybridization technique. The microparticles of alumina and boron carbide were reinforced into cast Al alloy (6061) in a systematic varying ratio (i.e.100/0, 75/25, 50/50, 25/75 and 0/100) to prepare the hybrid metal matrix composites via stir casting method. The mechanical properties (i.e. tensile, impact, hardness and flexural) of the prepared composites were investigated as per ASTM standards. Furthermore, microstructural analysis of unfractured and fractured composite samples was also carried out using Scanning Electron Microscope. It was observed that hybrid composites comprising of microparticles revealed an enhanced tensile, flexural and hardness properties, and reduced impact energy and porosity as compared to Al alloy and single reinforced metal matrix composites. The highest values of tensile strength and modulus were offered by a hybrid composite (B50A50), which was 40% and 52.12% higher than that of Al alloy. Furthermore, there was an improvement of 105.72% in flexural strength and a reduction of 23.88% in impact energy for composite B50A50 than that of Al alloy. The present developed hybrid metal matrix composites can be proposed to be used in automobile parts and construction applications.

“…Similarly, Durmus et al [5] used agehardening on AA2014, whereas Aksoz and Bostan [6] studied the effect of aging and cryo-aging treatment on microstructure and hardness of AA2014-SiC MMCs. Similarly for improving wear behavior, Canakci et al [7] used an artificial neural network to predict wear behavior of AA2014/B 4 C p MMCs, whereas Nagaral et al [8] investigated wear behavior of AA2014-ZrO 2 nano-composite by using a two-stage stir casting process. All these studies were conducted to improve the limiting properties of AA2014 alloy.…”

The present study aimed to improve the micro-hardness and wear properties of AA2014 aluminum alloy. Surface composite of AA2014 was produced using Al 2 O 3 as reinforcement by friction stir processing (FSP) technique. FSP was performed by using a constant traverse speed of 40 mm/min and two rotating speeds of 1000 and 1400 rpm. After FSP, the average grain size of AA2014 was reduced from 21.9 µm in base material to 9.2 µm in FSP with a rotating speed of 1000 rpm and 3.8 µm in FSP with rotating speed of 1400 rpm. Optical microscopy showed that the Al 2 O 3 reinforcement particles were distributed homogeneously in AA2014 after FSP. The micro-hardness test showed that the hardness property in AA2014/Al 2 O 3 surface composite was improved after FSP and was increased with an increase in rotating speed. The micro-hardness was improved by 30% after FSP. The wear test revealed that both the wear performance and coefficient of friction (COF) were improved after FSP. The COF was improved from 0.27461 in base material to 0.22570 in FSPed samples. Surface roughness test showed that the sample with more micro-hardness showed better surface roughness as compared to the other samples.
