“…Another work by M. Sabbaghian et al [7] revealed that the copper matrix composites prepared with TiC reinforcement, exhibited enhanced hardness and wear resistance due to refined grain structure obtained by FSP. Some other researchers attempted to obtain the dynamic properties of the friction stir welded joints using specific damping capacity with the help of simulation strategies [8]. A review study by V. Patel et al [9] summarizes that the effects of various process variables on the microstructure and physical properties of the aluminium composites prepared by FSP has been attempted in the recent literature.…”

Aluminium alloys, having high strength, ductility, and toughness, are useful structural materials. Composites of these with ceramic reinforcements improve the hardness and wear resistance, making them suitable for use in the aerospace and automobile industries. Since surface properties play a crucial role for most applications, the manufacturing of surface composites of aluminium alloys is recommended. For this purpose, Friction stir processing(FSP) is being utilized nowadays. It refines the microstructure with a homogeneous dispersion of reinforcements into the matrix and improves physical properties like surface hardness, wear resistance, strength, etc., while retaining the properties of remaining volume.The study aims to investigate and compare the temperature and vibration sensor data while manufacturing Al6061 alloy-based surface hybrid composites by using two different FSP tools. The FSP method is used for the fabrication of Al6061 alloy based composites with the copper and graphite powders mixture (1:1), reinforced into the matrix surface by using twoH13 tools with two different pin profiles - threaded cylindrical and plain cylindrical. Holes of different diameters and depths are drilled on the Al6061 matrix for reinforcement addition.This FSP process is investigated using a thermal gun and a Cross-Domain Development kit for temperature and vibration measurement. It is verified that both the temperature and vibration values are lower in the composites fabricated by FSP tool with threaded pin profile than that by FSP tool with plain pin profile. The processed samples are later investigated for the microstructure by Field Emission Scanning Electron Microscope and Energy-DispersiveX-Ray Spectroscopy tests. The reinforcements are dispersed more uniformly by the FSP tool with threaded cylindrical profile. This research can be used to further monitor and control properties like temperature, vibration, force, current, etc., to obtain a uniform reinforcement dispersion with improved mechanical properties during the surface composite preparation by FSP.

“…Fabrication of the metal matrix composite has been investigated using different techniques [1][2][3][4]. However, friction stir processing (FSP) is the most advanced method used to fabricate surface and metal matrix composites in a solid-state [5][6][7][8][9][10]. The improvement is due to the stirring action of FSP reflected on the microstructure refinement of the processed material.…”

In this paper, AA5250 aluminum sheets are reinforced with boron nitride (BN), silicon carbide (SiC), aluminum oxide (Al2O3), and vanadium carbide (VC). The nanocomposites metal matrix are manufactured using friction stir processing (FSP). A novel analytical comparison based on an assessment of mechanical, physical properties and the cost of manufactured materials was conducted to help the engineers and designers choose the most economically feasible nanocomposite. The results revealed extra grain refining for all composites in the stirred zone (SZ) due to the Zener-pinning mechanism. The smallest grain size was obtained in AA5250/BN, and it decreased 20 times that of the base metal (BM). The highest wear resistance was achieved in AA5250/SiC, followed by AA5250/VC and AA5250/BN. The lowest coefficient of friction was obtained for AA5250/BN due to the self-lubrication property of BN; which was μ = 0.28. SiC AA5250 had the highest hardness, increasing three times more than the base metal in terms of its hardness. There was a detailed discussion of the probable explanations for the improvements. However, the outstanding characteristics of the BN nanoparticles, the AA5250/BN was reported to be lower than the AA5250/SiC. In comparison, the AA5250/SiC nanocomposite exhibits the optimum value due to its fitting for different properties relative to the cost.

“…The refined grains significantly affect the dynamic properties of alloys and their composites regarding the impedance of the refined grains of the transmitted excitation source. Fewer investigations have discussed the impact of alloying elements on the dynamic properties [30][31][32]; hence, the effect of refined grains in addition to Al 2 O 3 nanoparticles using friction stir processing showed a significant improvement in the dynamic behaviour [33].…”

In this investigation, aluminium Al-2.5% Mg cast alloy was modified by adding 0.5 Ti and 0.1 B wt % modifiers to investigate their impact on the dynamic behaviour, as well as the mechanical and microstructure properties. The dynamic properties were analysed experimentally using a free vibration impact test and predicted using finite element methods. This study used a high-resolution polarised optical microscope to analyse the microstructure of the studied alloys and X-ray Powder Diffraction (XRD) analysis to determine the developed phases. Microstructure and mechanical properties were mostly enhanced as a result of grain refining during solidification and through the metal segregation process. The microstructure analysis of the modified alloy showed a significant improvement in the grain refinement; hence, the grains were 10 times finer than the cast alloy. The modified Al-2.5% Mg/Ti-B alloy demonstrated reduced inter-granular corrosion (IGC) than the Al-2.5% Mg standard cast alloy. By incorporating Ti-B modifiers into the composition of the cast Al-Mg alloy, the ultimate tensile strength (UTS), strain (ε), and hardness values (HV) were increased by 30.5%, 100%, and 18.18%, respectively. The dynamic properties of the modified alloy showed an enhancement in the resonant (fn) and damping ratio (ζ) by 7% and 68%, respectively. The predicted resonance frequencies of the investigated alloys showed results close to the experimental dynamic tests.
