“…To circumvent this problem, Shamsipour et al utilized electromagnetic stirrers to fabricate aluminium matrix nanocomposites by optimising the parameters which led to superior wear behaviour [24]. Further, study showed the intermetallic particles were evenly dispersed with lower stress concentration points throughout the Al-Si metal matrix when using electromagnetic stirrers [25]. Even with these techniques, there have been few reports that state that ultrasonic assisted double casting techniques could hardly eliminate the porosity due to lack of external pressure.…”

This study emphasis on a novel fabrication technique to fabricate hybrid cermets using Al 6061 alloy with nano sized SiC, Al2O3 and TiO2 as reinforcements. During the fabrication process, the melted pool was ultrasonicated to disperse nanoparticles at 20 kHz for 5 min and pressure of 50 MPa was applied to eliminate voids. The influence of nanoparticles on physical, thermal and mechanical properties were evaluated by tensile, wear and thermal studies. Cermets with Al2O3 reinforcements showed higher mechanical performance compared to Al alloy. This enhancement could be related to the uniform distribution of Al2O3 with refinement in grain size of Al alloy which was observed via surface analysis. The morphological studies provided justifiable evidence of homogeneous distribution, nominal cluster along with agglomeration and cavities shrinking on the cermets. The agglomeration of nanoparticles along with SiC protected the cermet in corrosion and abrasive wear by ~ 97% and ~ 71%. The study evidenced the novel fabrication method using ultrasonic rheo-squeeze casting led to improvement in mechanical and thermal properties of the hybrid cermets. Graphical abstract

In this article, A6061 and its reinforcement particles like aluminium oxide/glass fibres/SiCp/B4C (4% and 5%) with mixed composite and aluminium oxide/SiCp/B4C mixed without glass fibre composite are produced with different proportions using the stir casting method. Here, some experimental study is carried out on the composite layer through scanning electron microscopy and XRD test to show the influence of the reinforcement on A6061, and the percentage of gold-silver-copper (AuAgCu), aluminium-zinc (ZA), and palladium deuteride is increased in this composition and justified through the graphical representation of the XRD image. Mechanical properties of the stir casting composites were evaluated through microhardness, wear test under 200 rpm and 300 rpm and 20 N and 50 N, and tensile tests. The results were compared with the properties of the base metal, with glass fibre reinforcement specimen and without adding glass fibre specimen; this will help us to check the strength and weakness of the glass fibres in A6061.

Applying aluminum composite in the defense, aerospace and automotive industries depends on how they behave during the elasto-plastic form change. In addition to the factors responsible for changing the form of the alloy, many other factors have an impact on the behavior of the composite form change. In this study, the effect of casting type on the mechanical properties of Al-Si nano composites has been investigated. Due to the proper distribution of reinforcing particles, tensile strength in compo casting sample in semi-solid state is higher than sand casting and squeeze casting. In all samples, the tensile strength of the heat-treated samples has increased by about 30%. Tensile strength in compo casting sample in semi-solid state was obtained with higher nano particle reinforcing particles, which can be explained by the fact that the percentage of elongation in micro samples was lower than that of nano composite samples.
