“…e tensile properties of an aluminum-7Si-0.35 magnesium alloy matrix supplemented with varied weight percent of Al 2 O 3 in the range of 2 to 8 were improved owing to particle dispersal and particle-matrix connection [20]. An experiment [21] found that the characteristics of composites enhanced with a rise in fly ash material, which was next followed by microcoring and separation in the composite, all of which were linked to the composites' improved fly ash content. Composites made from L-aluminum alloys and reinforced with ZrC and fly ash [22,23].…”

Aluminum Alloy 5052/ZrC/fly ash composites’ tensile properties are changed by the addition of reinforcements and thermal exposure, according to this study. The precipitation hardening of samples manufactured with various weight percent of fly ash and zirconium carbide was employed to improve the properties under thermal circumstances. The tensile properties of reinforced and heat-treated specimens were studied in a series of scientifically-designed experiments. Tensile strength and yield strength rise up to 200°C, after which they begin to decrease slightly (i.e., 250°C) based on the results of the research. Adding reinforcements and exposing the composites to heat increases their elastic modulus which decreases the percentage of El of the composites substantially. Several factors contribute to composites’ increased strength and elastic modulus, the diffusion process, temperatures, and reinforcement composition. It is also possible to manufacture hybridized composite mechanisms for numerous automotive and aviation industries utilizing optimization studies, which interpolate the findings of several sets of parameters to make the process easier.

“…α-Al8Fe2Si was discovered to be absent in the 5083 and 6061 alloys. Therefore, α-Al15(Fe,Mn)3Si2 was considered the representative α-type Ferich IMC in this study [26]. Pandat also predicted trace amounts of reactant phases, such as Al13Cr2 and Al3Ti, but Al13Cr2 was not observed in this study.…”

Aluminum alloys 5083, 6061, and 7075 are prone to hot tearing under direct-chill casting conditions; the defects that form during solidification of those alloys are highly sensitive to variation in the alloying elements, with these elements commonly being Si, Fe, Cu, and Ti. This study investigates the influence of the morphology, content, and size of intermetallic compounds on the hot tearing behavior of the 5083, 6061, and 7075 aluminum alloys by combining a constrained rod casting technique, phase diagram calculation, and multiscale microstructural characterizations. The fishbone-shaped α-Al15(Fe,Mn)3Si2 in 5083 can serve as a path for crack nucleation and growth, and an increase in Si content results in Mg2Si assuming fishbone morphology, thereby increasing hot tearing susceptibility. The amount of plate-like β-Al5FeSi is the primary factor controlling the hot tearing susceptibility of 6061. For 7075, increasing the Cu content can greatly enhance the remaining liquid fraction, feeding, and hot tearing susceptibility. For all three alloys, TiB2 grain refiner minimizes hot tearing. This study elucidates the influences of the amounts of Fe, Si, Cu, and TiB2 grain refiner on hot tearing susceptibility. The findings can help establish compositional control standards for the 5083, 6061, and 7075 aluminum alloy series, particularly when the recycling rate must be increased.

“…[7] The diffusion of Ce at low temperatures is also difficult, so it is not expected for the predicted Al 10 CeFe 2 phase to transform into Al 13 Fe 4 or a-AlFeSi phase at lower temperatures. [22,23] Since the Si levels for the experimental alloys are within 0.04 wt pct and Si is not expected to interact with Fe, the effect of the Si impurity was not investigated in this work.…”

Iron (Fe) has been considered a major impurity since it is detrimental to the mechanical properties of many cast aluminum alloys due to the formation of Fe-containing brittle intermetallic phases. Fe is found naturally as an impurity in bauxite ore, resulting in Fe contamination of aluminum alloys with increasing contamination from current recycling practices. The Al–Ce–Fe system was investigated using CALPHAD (CALculation of PHAse Diagrams) modeling and experimental casting techniques. It was found that additions of Fe to the Al–Ce system are beneficial to the strength (slightly) and ductility (significantly) of the ternary alloys, which is attributed to the formation of fine metastable Al8CeFe2 phase with aggregate morphology and equilibrium Al10CeFe2 phase, suppressing coarse proeutectic Al11Ce3 phase in near-eutectic Al–Ce alloys. Heat treatment study showed that the metastable Al8CeFe2 phase transforms to predicted equilibrium Al10CeFe2 phase at 500 °C, with essentially no intermetallic or grain coarsening; thus, the alloy displayed excellent property retention. The Al–Ce–Fe alloy system offers opportunities for sustainable, recyclable alloy development using low-cost Fe and low-cost cerium (a byproduct of rare-earth extraction).
