“…Dinaharan and Murugan (2012b) carried out FSW of AA6061/ZrB2 composites and studied the effect of FSW process on the microstructure, mechanical and wear properties of the joints. Besides all these, considerable work was also carried out on the application of friction stir processing (FSP), which is utilized for producing MMCs, so as to improve mechanical properties compared to the unreinforced alloys (Chen et al 2015, Pantelis et al 2016, Tabasi et al 2016, Narimani et al 2016. However, few papers can be found in the literature discussing the feasibility of dissimilar FSW between AMCs and monolithic alloys (Sharifitabar andNami 2011, Guo et al 2012).…”

A research on the microstructure and mechanical properties of the dissimilar joint was carried out so as to understand the effects of post-weld heat treatment (PWHT) on microstructural evolution, microhardness, tensile and flexural properties of the dissimilar friction stir welded (FSWed) joint. The results showed that there is a sufficient and rather complicated material mixing in the nugget zone (NZ). After PWHT, the grains in the joint area except for the NZ demonstrated a grain refinement with more homogeneous and equiaxed grains. Fine and clustered SiC particles in the NZ are confirmed by scanning electron microscope (SEM). In addition, the microhardness values of nugget zones both in as-welded and PWHT condition exhibited a higher Vickers compared to that of AA6061-O. Furthermore, a mean tensile strength of 183.30 MPa that demonstrates a 52.22% increase in tensile strength is also observed in the transverse tensile tests subsequent to PWHT. Considering the three-point bending test results, it is explicit that an increase of 121.96% in the bending extension is obtained as there is no significant increase in maximum bending force after the PWHT.

“…Most of the work on surface composite fabrication using friction stir processing have been reported using different Nano particle size reinforcement like silicon carbide (SiC) [16], titanium carbide (TiC) [17], boron carbide (B4C) [18,19,33], aluminum oxide (Al2O3) [20], titanium oxide (TiO2), AIN [21], Si3N4 [22], titanium diboride (TiB2) [23,24], zirconium diboride (ZrB2) [25], carbon particles like graphite [26], carbon nano-tubes [27], nanohydroxyapatite [28], etc. The selection of the reinforcement is depending upon the application of the component and compatibility of reinforcement and metal matrix.…”

Surface Modification of Aluminium alloy have a wide range of applications in aerospace industries, where high strength to weight ratio is required. Different nano-particle reinforcements have different effects on Aluminium alloy as a base material. In this review paper the effects and properties are studied for different nano particle size of reinforcing materials such as boron carbide nano particle. In this paper also studied different type of tool pin profile used for the surface modification of Aluminium alloy. Friction stir processing tool plays an important role for the surface modification of the materials. It decides what types of materials could be manufactured. Properties like hardness, tensile strength, wear resistance etc have been studied rigorously and been summarised. It's been observed that there is an enhancement in the properties of surface composites so formed on addition different particle of the reinforcing materials to Al alloy surface composites.

“…Additionally, several studies have reported that increasing the rotational speed and the number of passes leads to an ultimate increase in tensile strength. On the other hand, increasing the travelling speed leads to a decrease in the ultimate tensile strength [13][14][15][16][17]. However, an important consideration in surface composite fabrication, aside from the process parameters, is tool wear, which is an undesirable feature and obstacle for the quality of the workpiece.…”

In this paper, optimization of the fabrication parameters of an aluminum surface composite with respect to tensile strength and tool wear rate is reported. The surface layer was reinforced with SiC particles to improve the tribological properties of AA-5052. The Taguchi design with orthogonal array L8 was used for the experimental design, which included three processing parameters: the number of passes, rotational speed, and traversal speed. The experiment used optimal fabrication parameter searching to produce a multi-response prediction of both the tensile strength and tool wear rate. The experimental result was determined by grey relational analysis for multi-performance characteristics. Afterward, the prediction result of the optimal fabrication parameters was confirmed by repeated experiments to confirm the selection of optimal process parameters. The results revealed that the optimal fabrication parameters for multi-performance characteristics are two passes, rotational speed of 1000 revolutions per minute (RPM), and traversal speed of 30 mm/min (condition N2R1T2). These showed high tensile strength (229.90 MPa), low tool wear rate (0.0851), and a uniform distribution of SiC particles in the matrix. In addition, grey relational analysis showed that the parameter priority was 51.68% for rotational speed (the most significant process parameter), 36.18% for transversal speed, and 7.05% for the number of passes. Therefore, the grey-based orthogonal array Taguchi method can optimize multi-performance characteristics through the setting of process parameters for friction stir processing of an aluminum surface composite.
