“…Pardeep Sharma et al [ 40 ] reported that the sound integrity closeness between the Si 3 N 4 /graphite contents and the AA6082 alloy augmented the UTS of the AAMCs. Jebeen Moses et al [ 41 ] have described the influence of blade angle, stirring speed, and stirring time on the hardness and UTS of the AAMCs. Shalaby and Churyumov [ 42 ] observed that the load transfer between the hard AlNp and soft matrix A359 alloy results in strengthening and improved tensile strength.…”

In the current research, AA6082 aluminium alloy matrix composites (AAMCs) incorporated with various weight fractions of titanium diboride (0, 3, 6, and 9 wt%) were prepared via an in situ casting technique. The exothermic reaction between inorganic powders like dipotassium hexafluorotitanate (K2TiF6) and potassium tetrafluoroborate (KBF4) in molten Al metal contributes to the development of titanium diboride content. The manufactured AA6082-TiB2 AAMCs were evaluated using a scanning electron microscope (SEM) and X-ray diffraction (XRD). The mechanical properties and wear rate (WR) of the AAMCs were investigated. XRD guarantees the creation of TiB2 phases and proves the nonappearance of reaction products in the AMCs. SEM studies depict the even dispersion of TiB2 in the matrix alloy. The mechanical and tribological properties (MTP) of the AAMCs showed improvement by the dispersion of TiB2 particles. The WR decreases steadily with TiB2 and the least WR is seen at nine weight concentrations of TiB2/AA6082 AAMCs. Fabricated composites revealed 47.9% higher flexural strength and 14.2% superior compression strength than the base AA6082 alloy.

“…Al matrix composites [1] have been paid great attention due to their high specific stiffness and strength, good corrosion resistance, low coefficient of thermal expansion and high dimensional stability. Compared with other ceramic particles (such as Al 2 O 3 , TiB 2 , B 4 C, TiC and Si 3 N 4 ), SiC particles have the comprehensive advantage of low cost, low density, high elastic modulus, high thermal conductivity and good bonding with Al matrix [2]. Therefore, SiC particles reinforced Al matrix composites have been extensively explored and are widely used in aerospace industry [3] and brake systems for automobile [4].…”

In the present work, the wire electrical discharge machining (WEDM) process of the 65 vol% SiCp/2024Al composite prepared by pressure infiltration methods has been investigated. The microstructure of the machined composite was characterized by scanning electron microscope, the average surface roughness (Ra), X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy (TEM) techniques. Three zones from the surface to the interior (melting zone, heat affected zone and unaffected zone) were found in the machined composites, while the face of SiC particles on the surface toward the outside was ''cut'' to be flat. Increase in Al and Si but decrease in C and O were observed in the core areas of the removed particles. Si phase, which was generated due to the decomposition of SiC, was detected after the WEDM process. The irregular and spherical particles were further observed by TEM. Based on the microstructure observation, it is suggested that the machining mechanism of 65 vol% SiCp/2024Al composite was the combination of the melting of Al matrix and the decomposition of SiC particles.

“…31 The preheated particulate, use of inert gas during discharge of particles in the matrix, and stirring speed of 300 rpm will help in better wetting of reinforcement in the matrix. 32 For the homogenous distribution of reinforcement, the stirring speed should be high and the duration of stirring should be amended. The rate of solidification has its significance in the distribution of particles.…”

Aluminum metal matrix composites are a new class of materials that have gathered more attention from many materialists. Especially, the automotive components like a piston, cylinder block, brake drum, etc., fabricated by different reinforcement, which has exposed better performance over conventional engineering materials. Aluminum composites are generally fabricated by stir casting technique due to simplicity in operation and adaptive to mass or job order production. The paper provides a background for the readers interested in the production of metal matrix composites through stir casting. Based on the literature assessment, the special attentions taken by the researchers to enhance the uniform distribution of particle to avoid agglomeration are discussed. The composite performances mainly depend on the aluminum matrix, particle size, the quantity of reinforcement, preheating temperature of reinforcement, and processing parameters such as stirring speed, stirring time, and wetting agents. The selection of two reinforcements and their suitable parameters for wetting are attaining interest by many researchers and maybe opted as future scope.
