“…Due to stronger bonding and interstitial strengthening, thermal treatment is necessary in order to improve the composites' tensile characteristics. A similar study in [29] found that the mechanical characteristics of aluminum-fly ash compounds can be enhanced by thermal treatment. Using different weight percentages of fly ash and heat treatments on composite specimens, they were able to improve the mechanical characteristics by altering the crystalline structure, which was then followed by different weight percentages and particle sizes of fly ash.…”

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.

“…Prolonged heating provides more time for the recrystallization process, resulting in finer grains and increased micro hardness. Longer heating durations also facilitate the development of a more favorable microstructure for wear resistance [31]. In contrast, the furnace cooling environment significantly enhances the GRG value when compared to water and atmospheric cooling.…”

Aluminium Metal Matrix Composites (AMMCs) are the essential need for applications such as aerospace, aircraft, marine, transport and automobiles due to their best mechanical, corrosion and tribological behaviour. In this research, Alumnium alloy 7075 is chosen for matrix material because of its much more need of mechanical, corrosion and tribological properties enhancement. The nano zirconium di oxide (ZrO2) is chosen for reinforcement to fulfil the properties requirement of AA7075 for various applications. The AA7075/wt. % Zr02 (x= 0, 5, 10, 15 and 20) composites are prepared by stir casting route. The fabricated composites are subjected to tensile strength and density test to determine the best combination of AA8009 based composites. The best combination of AA7075 based composites is subjected to EDAX and SEM test to determine the presence of elements of reinforcement and matrix material. The stir casted AA7075 based composites are further subjected to hardening under different conditions to enhance their required properties. The input parameters of hardening are age hardening temperature, hardening duration and cooling environment. The chosen response parameters are micro hardness and wear loss. The micro hardness and wear resistance of composites are determined by employing tensile Vickers hardness tester and pin on disc equipment. The optimization is done by using Grey Relational Analysis (GRA). The optimized age hardening process parameters are hardening temperature (400°C), hardening duration (270 minutes) and cooling environment (Furnace cooling). The obtained higher micro hardness and lower wear loss of confirmation test combination specimen is 138 HV and 27 mg respectively.

“…The predicted and actual values of the tensile strength, hardness BHT, and hardness AHT are shown in figure 8. Based on the selected input variables, the evaluation was carried out and then analysed [33][34][35][36][37]. The validation outcomes demonstrated that there is a linear path because the approximations derived from the model and the real values are similar.…”

Aluminum matrix composites have gained interest recently because they are more efficient, lighter, and less expensive. The purpose of this current study was to examine the effects of various casting operating conditions, including stirring temperature, stirring time, and stirring speed, on the casting process. Determining the optimum processing parameters to achieve significant outcomes could be the most daunting problem while casting a specimen. Box-Behnken design based on response surface methods was used to investigate the effects of stir casting factors on the mechanical properties of AA6063 - 4 % TiB2 composites. The response's real value, which includes hardness before heat treatment, hardness after heat treatment, and tensile strength, is reflected in the surface plot created by statistical software. F-ratio is often used in an ANOVA table to examine how operational variables affect properties of the material. Dispersion of the reinforcements mixture has been studied and characterized under scanning electron microscope and x-ray diffraction spectrometer. The optimum temperature, time, and rotational speed were 823.662°C, 15 minutes, and 300 rpm. Composite materials made from aluminium 6063 are extensively used in the fabrication of lightweight aircraft components like ribs and fuselages.
