“…Moreover, in the EC specimens, the highest UTS was achieved upon the addition of 2 wt% sea sand and then decreased upon the addition of the sea sand particles. The increase in the tensile strength is related to the presence of ceramic compounds (Al 2 O 3 , SiO 2 , Fe 2 O 3 ) in sea sand [ 40 ]. Previous research has stated that in composites, there are several strengthening mechanisms, including grain refinement, particle strengthening, and strengthening due to thermal differences [ 41 ].…”

Aluminium matrix composites (AMCs) are widely used in various applications because of their excellent properties; however, their lightweightness limits their broad application scope. Various ceramic compounds are used as reinforcements in AMCs, such as Al 2 O 3 , SiC, ZrO 2 , and TiO 2 . However, the use of ceramic compounds results in high production costs in AMC manufacturing. Thus, the substitution of reinforcement particles with various organic and industrial waste reinforcements is required. In line with the research trend of using industrial waste materials such as rice husk ash, red mud, and fly ash, this study uses sea sand as an AMC reinforcement. Sea sand is used because it primarily contains SiO 2 and Fe 3 O 4 ceramic compounds and, thus, can be used as a reinforcement. This study aims to determine the physical and mechanical properties of an AA6061–sea sand composite. Sea sand was subjected to electroless coating to increase its wettability before the stir-casting process. The as-prepared composite was manufactured by the stir-casting method upon the addition of 2–6 wt% sea sand. Composite characterisation was carried out through Brinell hardness and tensile tests. The results showed that the electroless-coated composites possessed lower porosity and, therefore, higher hardness and ultimate tensile strength than the non-electroless-coated composites.

Among the various types of manufacturing process methods for discontinuous metal matrix composite, stir casting is the best suitable manufacturing process to fabricate particulate reinforced metal matrix composite. Its benefit is its simplicity, durability, and adaptability. The main issue in this process is proper wetting of reinforcement in aluminium matrix material. Only proper wetting results in a homogeneous dispersion of reinforcement material, and these homogeneous dispersions help to improve the properties of metal matrix composite material. The purpose of this paper was to discuss the outline of the stir casting process, process parameters, and the contribution effect of process parameters. This paper also presents about of the conditions should follow during the addition of reinforcement material and matrix material pouring in mould cavity. This paper also discusses the conditions that must be met during the addition of reinforcement material and matrix material pouring in the mould cavity. This paper also looked into the impact and contribution of stirring casting time, speed, and temperature in aluminium metal matrix composites, as well as processing issues in aluminium metal matrix composites, challenges, and research opportunities.

“…Different merits of stir casting method were explained by them as compared to other methods. The wear mechanisms and performance of novel boron nitride based tools and super-hard diamond in machining Al-SiCp MMC was investigated by Dhaneswara et al [17] in which the behavioural studies of SiCp nano particle reinforced Al A356 with Sr-modifier was synthesised by the method of stir casting. Their results concluded that nano composite material achieved its ultimate tensile strength of 176.1MPa and elongation of 6.92% by the addition of 0.25% of SiCp nano particle.…”

The current research paper discusses the characterization and machining (turning) operation of aluminium (Al) and silicon carbide nano particle (SiCp) nano composite. The paper reveals proper distribution of silicon carbide nano particles (25nm) with aluminium metal matrix. Initially, tensile test has been carried on metal matrix nano composite to study its different properties. It was noticed that the properties of Al-SiCp increases by increasing the weight percentage of SiCp. Viker hardness test has also been conducted to find out the hardness of metal matrix nano composites. Different techniques i.e. Optical microscopy EDX-Analysis were utilized to find out various ingredients of the nano-composite material. The experimental study was carried out using Taguchi L 16 orthogonal array by taking three different factors at four different levels each. The response parameters i.e. flank wear of coated carbide insert and surface roughness of Al-SiCp has been optimized by using Principal Component Analysis (PCA). Various graphs like main effect plot and normal probability plot have been plotted and studied properly. Different optical images of coated insert carbide tools (Insert CNMG 12040822TN 6010) at different runs were conducted to visualize the effects of process and response parameters. From the ANOVA table, it was found that cutting speed as well as depth of cut are found to the most vital parameters in influencing the responses for VBc and depth of cut and feed are found to the most significant parameters in influencing the responses for Ra.
