“…However, the relation between the particle volume fraction and the mechanical properties is not always direct. In an AMC system of AA7075 with SiC particles, it was shown that a small addition of SiC particles (1%) improved the material’s strength, whereas the addition of 5% caused the strength properties to deteriorate compared tothe original matrix material [ 14 ].…”

The mechanical response and failure of Al-TiB2 composites fabricated by Spark Plasma Sintering (SPS) were investigated. The effective flow stress at room temperature for different TiB2 particle volume fractions between 0% and 15% was determined using compression experiments on cylindrical specimens in conjunction with an iterative computational methodology. A different set of experiments on tapered specimens was used to validate the effective flow curves by comparing experimental force–displacement curves and deformation patterns to the ones obtained from the computations. Using a continuum damage mechanics approach, the experiments were also used to construct effective failure curves for each material composition. It was demonstrated that the fracture modes observed in the different experiments could be reproduced in the computations. The results show that increasing the TiB2 particle volume fraction to 10% results in an increase in material effective yield stress and a decrease in hardening. For a particle volume fraction of 15%, the effective yield stress decreases with no significant influence on the hardening slope. The ductility (workability) of the composite decreases with increasing particle volume fraction.

“…7d that the pattern of solidification is affected by the absorption of strengthening debris (SiC debris). According to earlier AFM research for aluminium compounds, the first grains size are drawn-out but no longer possess a good grain shape because of the alloys' low hardness [25]. As seen in Fig.…”

A crucial and costly step in the whole manufacturing process is the precision and super finishing procedure. A step of final finishing is involved in the production of precision components. It accounts for a respectable portion of the cost of production overall, is mostly uncontrolled, and requires a lot of manpower. Abrasive finish methods are being developed to address issues including high direct costs and the production of precision components with particular characteristics for finishing inaccessible places. A vast number of cutting blades with arbitrary orientation and shape are used in the abrasive finishing process. Due to their ability to complete a variety of form geometries with the appropriate dimensional accuracy and surface polish, abrasive fine procedures are often used. The unconventional finishing method known as AFM (abrasive flow machining) presses abrasive viscoelastic polymer on the surface of work piece. Al7075/SiC NMMCs’ internal rounded and hollow surfaces are completed using an AFM trial procedure that is constructed and designed in conjunction with specially produced medium. Workpieces are created using a lathe shortly after stir casting metal matrix nano composites with cross sections of 25 mm in diameter and containing 1 percent,1 ,2,3,4 nano-Sic (50 nm) by weight. Extrusion pressure abrasive particle grain size number of cycles were evaluated for their surface roughness (Ra) than material removal (MR), respectively. The evaluation of the material’s qualities, such as density, hardness, and tensile strength The improvement in the surface completeness of these NMMCs is further shown by the scanning Microscopy OM, EDS SEM, and XED analyses.

“…Microstructural properties of Al-4.5Cu alloy reinforced with TiC particulate are studied and optimum process parameters for stir casting are derived (Das et al 2016). In a study on reinforced Al7075, the parent group is evaluated and reinforcement of 6% SiC in Al7075 shows improved density, hardness, bending strength, and elongation is observed (P. Kumar et al 2018). On review of the following pieces of literature, it is observed that research work by (P. Kumar et al 2018) showed identical findings, thus it can be said that the work is closely studied for this research.…”

The aim of this research is to fabricate an aluminium hybrid metal matrix composite reinforced with a 15% weight fraction constituting 7.5% of silicon carbide and 7.5% of fly ash using the stir casting method under controlled process parameters and compare tensile strength, compressive strength, hardness and corrosion resistance with pure as-cast Aluminium 6061. Materials and Methods: Samples of dimensions 150mm x 150mm and thickness 10mm are prepared under Identical conditions adhering to standards. For g power calculations (threshold level: 0.20, confidence interval: 80%) gives a sample size of 80. Mechanical tests are taken individually on each sample for 20 samples of the experimental group (AHMMC) and control group (As-cast AL6061) as per ASTM standards. Results: One-way ANOVA using SPSS software shows that AHMMC with a 15% weight fraction of SiC and Fly ash has a significantly higher tensile strength (38.97 MPa), compressive strength (55.91 kN), and hardness (76 HV) but has slightly lower corrosion resistance (1.659 mm/year) than that of as-cast Al6061 with a significance level of 0.036 (p<0.05). Conclusion: Within the limitations of this study, It is revealed that AHMMC with a 15% weight fraction of SiC+Fly ash exhibited enhanced Mechanical and physical properties when compared to as-cast Al6061.
