Mechanical behavior of Al-matrix nanocomposites produced by stir casting technique

A review on mechanical properties of aluminium-based metal matrix nanocomposites

“…This paper provides a literature review of the following mechanical properties: hardness, elasticity, elongation, tensile strength and fracture strength. All the mentioned properties were studied by the researchers to analyse the improvement of the mechanical properties that influence the selection of materials [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Table 1 shows the mechanical properties of various nanocomposites with an aluminium matrix.…”

“…Researchers have dedicated significant efforts to the development of aluminium nanocomposites with ceramic reinforcements, such as: SiC [5,17,18,[26][27][28]33]; Al 2 O 3 [6,[13][14][15][16][17][18]21,[23][24][25]29,31,32,34]; TiC [24]; ZrO 2 [16,19]; B 4 C [14,31]; TiO 2 [20]; TiB 2 [15,32,34]; Gr [21] and many more, obtained by different fabrication methods. Numerous researchers have reported that the production process, particle size, grain size, and the connection between the matrix and the reinforcement and dislocations, have an obvious effect on the mechanical characteristics of the composite.…”

“…Mohanavel et al [25] applied the stir casting method for the production of composites reinforced with Al 2 O 3 particles and by the SEM analysis, they showed a homogeneous distribution of particles in the matrix alloy 6082. Al-Salihi et al [29] also proved improvements in tribological and mechanical characteristics, which indicate the success of the applied method in obtaining nanocomposites reinforced with hard Al 2 O 3 particles.…”

“…Based on the analysed literature, it is noticed that the hardness of the material is affected by the type of base material, type and size of reinforcement and its weight/volume content in the nanocomposite [9,13,[15][16][17][18][19][20][21][24][25][26][27][28][29][30][31][32]34,49].…”

“…With the addition of only Al 2 O 3 reinforcement [25,29,49] to the aluminium nanocomposites, certain improvements in tensile strength and yield strength were observed. However, with the combination of reinforcements, much greater improvements were achieved.…”
