Fly ash is a light byproduct produced when pulverized coal is burnt in suspension-fueled furnaces in power plants. Separating the recovered fly ash from the exhaust gases. Due to its distinct physical and chemical properties, it is utilized in a wide variety of industrial and building applications. These applications include the production of cement and concrete, the stabilization of liquid waste, and hydraulic mining backfill. Fly ash has the potential to enhance the physical and mechanical properties of aluminum castings, as well as reduce their costs and increase their densities, all while lowering their prices. This research investigated the effect of fly ash incorporation on the mechanical properties of the aluminum casting alloy ZA8. Investigated were the cast and heat-treated varieties of unreinforced ZA8 and its metal matrix composite of 15% ferrous, 20% nickel, 10% fly ash, and 10% magnesium carbide. According to the results, the quantity of fly ash in the melt affected the

The present investigation pertains to effect of different levels of modifiers (Na) in the Al-11.1Si hypo-eutectic alloy casting process. The investigation deals with the porosity analysis of the hypo-eutectic Al-Si alloy casting with varying master alloy, composition and holding time. The modifiers used for the investigation is sodium. Four levels of compositions addition of modifier as sodium is selected for the casting process which are 0.03%, 0.06%, 0.09%, &0.12%. The holding times selected for each composition are 10min, 20min and 30min respectively. The introduction sodium to an Al-Si alloy results in a complete transformation of Si particles, changing them from coarse plates to fine fibres, irrespective of the cooling conditions. The reduction in eutectic growth temperature due to sodium addition was consistently associated with the degree of modification, regardless of the initial microstructure coarseness. Employing modification treatment significantly enhances elongation to

Aluminum alloys are employed in agricultural equipment, aerospace sectors, medical instruments, machinery, automobiles, etc. due to their physical and mechanical characteristics. The geometrical shape and size of the parts are modified in turning operation by using a single-point cutting tool. A356 aluminum alloy is widely used in various engineering sectors, hence there is a necessity to produce A-356 components with quality. The inappropriate cutting parameters used in turning operation entail high production costs and reduce tool life. Box–Behnken design (BBD) based on response surface methodology (RSM) was used to design the experiments such that the experiment trials were conducted by varying cutting parameters like N-spindle speed (rpm), f-feed rate (mm/rev), and d-depth of cut (mm). The multi-objective responses, such as surface roughness (SR) and metal removal rate (MRR) were analyzed with the desirability method. The analysis of variance (ANOVA) represents the significant

The hot corrosion studies for the die-casted magnesium (Mg) silver (Ag) alloys are carried out through the steam heating route. The Magnesium Silver (QE22A) alloy is fixed under the top lid of the pressure cooker (2 liters) and filled with water and 5% salt (NaCl) solution. The specimens are treated with different time intervals (10, 20, and 30 minutes), with the steam temperature maintained at 100°C around the specimen. The results showed an increase in the corrosion rate with the increase in the steaming time. Further, after the specimens have cooled down to room temperature, similar experiments are repeated for the second and third cycles. Here the formation of the oxide layers over the specimen has reduced the corrosion rate. The structural, surface study was carried out through scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive spectroscopy (EDS) to know the corrosion behavior on the specimen. From the microstructure, it is noticed that the average

Additive manufacturing (AM) provides significant geometric design freedom for the cooling of high pressure die casting (HPDC) tools. Designing cooling channels that can achieve a uniform temperature throughout the tool-cast interface during the moulding process can limit part warping and sink marks, internal part stresses, and increase tool life. However, the design of the embedded cooling channels requires high computational resources to model the heat transfer process for the cast, mould, and coolant from the moment aluminium is injected into the cavity until the injection for the next cycle. To enable the examination of the effect of various parameters, a simplified 3-D CFD conjugate heat transfer model is introduced by considering the experimental observations. The model decouples the cast part from the mould. A volumetric heat source term is added to the energy equation to represent the solidification energy, and accordingly the heat flux is evaluated on its surface that has been

The effect of Portevin-Le Châtelier (PLC) effect and its influence on the mechanical properties of aluminum, have aroused interest in the scientific community, aiming possible applications in the industry. The respective effect has been commonly observed in the solid solution state in Al-Mg alloys. Therefore, the objective of this work is to analyze the effect of the PLC phenomenon on the mechanical properties of the material with additions of 2% and 6% of Mg in the base alloy of Al-0.18%. For this purpose, the alloys were cast in a muffle furnace and cast in copper mold (section of the properzi wheel), followed by cooling in water. Samples were cut and machined to 9.5 mm in diameter. Subsequently, they underwent sanding and polishing processes in order to obtain their macrostructures. The results obtained in this step show that Mg refined the grain structures. The tensile test was performed for mechanical characterization. The results showed that increasing Mg contents resulted in
