“…A study by [19] found that inoculation of the composite reinforcements improved the properties of aluminum-fly ash-ZrC hybrid composites after a heat treatment procedure. 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.…”

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.

“…This is primarily attributed to the lower layer's contact with the substrate, experiencing repeated heat accumulation and dissipation, resulting in a notable reduction in material hardness due to thermal cycling. In Figure 19d, it can be seen that the hardness in the middle does not vary much under different parametric conditions, and NO.1, NO.2, and NO.3 can reach 58.4%, 58.5%, and 55.2% of the hardness of the parent material (113.1 HV [49]) at the middle, respectively. The hardness of NO.3 is higher at AS and RS, reaching 59.8% and 56.6% of the base material, respectively, which may be due to the combined effect of the increased precipitation of Mn elemental compounds, as shown in Figure 11, the deformed grains with an orientation distribution, as shown in Figure 14, and the texture enhancement, as shown in Figure 15.…”

“…Notably, the grains in samples NO.2 and NO.3 regained their orientation, indicating secondary deformation subsequent to recrystallisation. Figure 12b,e,h show the grain size distributions of the AFSD samples for the parametric conditions of NO.1, NO.2, and NO.3, respectively, with the average grain sizes of 2.32 µm, 2.37 µm, and 3.04 µm, The degree of grain refinement is about 6.7-8.8% (34.4 µm [49]) of the depletable substrate, and most of the grains are smaller than 10 µm. Significant grain refinement occurred during the AFSD process.…”

Additive friction stir deposition (AFSD), in which molten metal materials are formed into free-form stacked structural parts according to the path design, may have a wide range of applications in high-efficiency mass production. In this study, experiments were conducted for the rotational speed in the AFSD parameters of 6061 aluminium alloy bars to investigate the effects of different rotational shear conditions and heat inputs on the properties of the deposited layer for diameter bars based on the analysis of the micro-morphology, micro-tissue composition, and mechanical properties. The width and thickness of each layer were constant, approximately 40 mm wide and 2.5 mm thick. The particle undulations on the surface of the deposited layer were positively correlated with the AFSD rotational speed. Continuous dynamic recrystallisation in the AFSD process can achieve more than 90% grain refinement. When the rotational speed increases, it causes localised significant orientation and secondary deformation within the recrystallised grains. The ultimate tensile strength of the deposited layer was positively correlated with the rotational speed, reaching a maximum of 211 MPa, and the elongation was negatively correlated with the rotational speed, with a maximum material elongation of 37%. The cross-section hardness of the deposited layer was negatively correlated with the number of thermal cycles, with the lowest hardness being about 45% of the base material and the highest hardness being about 80% of the base material.

Differing from metal alloys produced by conventional techniques, metallic products prepared by additive manufacturing experience distinct solidification thermal histories and solid−state phase transformation processes, resulting in unique microstructures and superior performance. This review starts with commonly used additive manufacturing techniques in steel−based alloy and then some typical microstructures produced by metal additive manufacturing technologies with different components and processes are summarized, including porosity, dislocation cells, dendrite structures, residual stress, element segregation, etc. The characteristic microstructures may exert a significant influence on the properties of additively manufactured products, and thus it is important to tune the components and additive manufacturing process parameters to achieve the desired microstructures. Finally, the future development and prospects of additive manufacturing technology in steel are discussed.
