Friction stir processing (FSP) is solid state novel technique developed to refine microstructure and to improve the mechanical properties and be used to fabricate the aluminium alloy matrix composites. An attempt is made to fabricate AA6061/TiB2 aluminium alloy composite (AMCs) and the influence of process parameters like rotational speed, transverse feed, axial load and percentage reinforcement on microstructure and mechanical properties were studied. The microstructural observations are carried out and revealed that the reinforcement particles (TiB2) were uniformly dispersed in the nugget zone. The Tensile strength and Hardness of composites were evaluated. It was observed that tensile strength, and hardness were increased with increased the rotational speed and percentage reinforcement of particles. The process parameters were optimized using Taguchi analysis (Single Variable) and Grey analysis (Multi Variable). The most influential parameter was rotational speed in single variable method and multi variable optimization method. The ANOVA also done to know the percentage contribution of each parameter

“…The hook is a kind of inherent feature in friction stir lap welding process [31], which is characterized by a crack-like The coarse alumina particles and kiss bonding defects will seriously affect the performance of the components, which must be avoided by using some special methods. In this study, the method of two-pass processing was taken in this study to eliminate the kiss bonding defects and refine the oxide particles, which is also used in friction stir processing by a few researchers [29,30]. The schematic illustration of two-pass processing during FSLW is shown in Figure 7.…”

Friction stir lap welding (FSLW) raises the possibility of fabricating high-performance aluminum components at low cost and high efficiency. In this study, we mainly applied FSLW to fabricate multi-track 2024 aluminum alloy without using tool tilt angle, which is important for obtaining defect-free joint but significantly increases equipment cost. Firstly, systematic single-track FSLW experiments were conducted to attain appropriate processing parameters, and we found that defect-free single-track could also be obtained by the application of two-pass processing at a rotation speed of 1000 rpm and a traverse speed of 300 mm/min. Then, multi-track FSLW experiments were conducted and full density multi-track samples were fabricated at an overlapping rate of 20%. Finally, the microstructure and mechanical properties of the full density multi-track samples were investigated. The results indicated that ultrafine equiaxed grains with the grain diameter about 9.4 µm could be obtained in FSLW samples due to the dynamic recrystallization during FSLW, which leads to a yield strength of 117.2 MPa (17.55% higher than the rolled 2024-O alloy substrate) and an elongation rate of 31.05% (113.84% higher than the substrate).

“…FSP technique makes use of a non-consumable rotating tool to induce heat into the material being processed [2,3]. The process has been used to applied to modify microstructural to improved mechanical properties through intense plastic deformation by grain refinement [4,5] The advantage of FSP include densification, homogeneity of the processed material and microstructural refinement, homogenization of precipitates in various aluminium alloys and composites materials [6][7][8].…”

Abstract. In this paper, friction stir processing (FSP) was used to refine the microstructure of the copper alloy using various parameters. The influence of the tool rotation and traverse speeds on the microstructural and mechanical properties of the processed copper alloy was measured and analyzed. Micro-hardness measurements were used to evaluate the mechanical properties of the material. The results show that copper alloy processed by FSP has an enhanced micro-hardness property than the unprocessed copper alloy, this makes the materials processed by FSP appropriate for use in industrial applications.
