“…Therefore, the gradual dispersion of the reinforcing particles throughout the aluminum matrix with sequential FSP passes resulted in a steady decrease in both grain size and HAB content ( Figure 8 c–f and Figure 9 a,b). A gradual grain refinement within the matrix of the aluminum-based composites with the number of FSP passes has been reported in the scientific literature [ 16 , 17 , 20 , 21 , 51 , 52 , 53 , 54 ].…”

The purpose of this work was the examination of microstructural evolution during the fabrication of an Al/Al2O3 composite by friction stir processing (FSP). In order to obtain new insight into this process, a longitudinal section of the produced composite was studied, and advanced characterization techniques (including electron backscatter diffraction and microhardness mapping) were applied. It was found that the reinforcing particles rapidly rearranged into the “onion-ring” structure, which was very stable against the subsequent dispersion. Specifically, the remnants of the comparatively coarse-scale particle agglomerations have survived even after 12 FSP passes. Therefore, it was concluded that three or four FSP passes, which are often applied in practice, are not sufficient to provide a homogeneous dispersion of the reinforcing particles. It was also revealed that the gradual distribution of the nanoscale Al2O3 particles throughout the aluminum matrix promoted a subtle reduction in both the portion of high-angle boundaries and the average grain size. These observations were attributed to the particle pinning of grain-boundary migration and dislocation slip.

“…The average hardness of the as-prepared Al 2024 aluminum alloy sheets was 97 ± 5 HV. After FSP, the hardness values in SZ decreased due to the softening effect in SZ (Figure 8a) [37,39,40]. The decrease in hardness values was about 20% compared to BM (Figure 8b).…”

In the present work, an advanced technique was applied to coat an Al 2024 alloy with a surface composite layer reinforced with various nanoparticles. The surface of Al 2024 aluminum alloy was modified with Ta2C, Al2O3 and multi wall carbon nanotubes MWCNTs nanoparticles by friction stir process (FSP). An improvement in the surface of the fabricated nanocomposite due to the refinement of the microstructure grains was achieved. In addition, a significant improvement in the hardness and wear behavior was observed. The reinforcement particles were incorporated into double and triple hybrid composite particles to determine the most effective combination for the controlled properties. The results showed that for the composite reinforced with a double hybrid of Al2O3 and MWCNTs, the microstructure grains of the fabricated nanocomposite surface were refined by 40 times. The hardness was significantly improved, i.e., it was increased by 48% by incorporating the triple reinforcement (Ta2C, Al2O3, and MWCNTs) into the surface of Al 2024 aluminum alloy. The results of wear properties were in agreement with the results of hardness; the maximum wear resistance was obtained for Al 2024-Ta2C + Al2O3 + MWCNTs, and the wear rate was reduced by 11 times.

“…Several other properties like surface hardness, wear resistance and coefficient of friction can be enhances by FSP [11][12][13]. Many researchers have investigated about the enhancement in surface properties with introduction of second phase particle materials through FSP [14][15][16][17][18]. The ability to create MMCs on the desired surface which enhanced the properties and durability of the material is the most unique advantage of the FSP [19][20][21].…”

Friction stir processing (FSP) becomes remarkable technique to create metal matrix composites (MMCs). FSP can be used to produce MMCs of different materials like aluminium, copper, magnesium, steel etc. Due the excellent mechanical properties like higher strength to weight ratio, higher corrosion resistance and lighter weight density brand aluminium as a material of choice for different structural application in different industries like defense, marine, automobile and aircraft. Many researchers have found that the microstructure as well as mechanical properties of aluminium can be altered through reinforcing particles like SiC, TiC, Al2O3 etc. Microstructure, mechanical and wear properties of aluminium base material can also altered by modifying different variables involved in FSP. This paper is a state of art of review of consequences of different variables of FSP on mechanical properties of aluminium metal matrix composites (AMMCs) fabricated through FSP method.This review article will also provide the future research direction for aluminium as a base metal.
