“…Figure 9 shows the engineering stress and strain curves of the unprocessed and friction stir-processed GTAWed joints in correlation to Table 6. A similar impact of FSP on tensile properties of materials was also reported in the literature [24,47,64]. Table 7 and Figure 10 shows the tensile test results for the friction stir-processed and unprocessed FSWed joints.…”

This paper presents the analysis of the friction stir-processed aluminium alloy 5083-H111 gas tungsten arc-welded and friction stir-welded joints. The comparative analysis was performed on the processed and unprocessed gas tungsten arc-welded and friction stir-welded joints of similar aluminium alloy 5083-H111. The results showed a clear distinction between the friction stir processed joints and unprocessed joints. There is a good correlation observed between the microstructural results and the tensile results. Ultrafine grain sizes of 4.62 μm and 7.177 μm were observed on the microstructure of the friction stir-processed friction stir-welded and gas tungsten arc-welded joints. The ultimate tensile strength for friction stir-welded and gas tungsten arc-welded before friction stir processing was 153.75 and 262.083 MPa, respectively. The ultimate tensile strength for friction stir processed friction stir-welded joint was 303.153 MPa and gas tungsten arc-welded joints one was 249.917 MPa. The microhardness values for the unprocessed friction stir-welded and gas tungsten arc-welded joints were both approximately 87 HV, while those of the friction stir-processed ones were 86.5 and 86 HV, respectively. The application of friction stir processing transformed the gas tungsten arc morphology from brittle to ductile dimples and reduced the ductile dimple size of the unprocessed friction stir-welded joints from the range of 4.90–38.33 μm to 3.35–15.59 μm.

“…And the peaks of Al 2 Cu broadened slightly owing to the refinement and straining of grains. 35 The intensity of Al 2 Cu precipitates in ACFSP sample was slightly higher than that of CCFSP and UWFSP samples. These results could be attributed to coarser precipitates in ACFSP samples due to frictional heat generated in the SZ.…”

The present paper studies the influence of different cooling media (water and cryogenic media) on microstructure, mechanical, and corrosion behavior of friction stir processing of AA2014. From the electron backscattered diffraction results, it was observed that the grain size in stir zone of air-cooled friction stir processing, dry ice-cooled friction stir processing, and underwater friction stir processing are 4.9 µm, 3.5 µm, and 0.9 µm respectively, and the fraction of high angle grain boundaries are more in underwater friction stir processing sample compared to other conditions. The ultra-fine grained structure (0.9 µm) was achieved in underwater friction stir processing due to uniform heat dissipation from the processing zone to the water. Mechanical properties such as hardness and strength were improved in underwater friction stir processing compared to other conditions. The fine precipitates formed in the underwater friction stir processing sample were distributed randomly at grain boundaries, and hence corrosion resistance was improved in underwater friction stir processing sample compared to other conditions.

“…The sever deformation increased the dislocations and microstructural changes lead to the improved tensile properties in the cast. [3]This work focuses on the reinforcement of quartz withAA6063.The synthesised composites were of volume percentage varying from 0 to 18% with an increment of 6%.The micro hardness and wear properties improved due to the better dispersion of the quartz particles [4].This work reports the reinforcement of Fly Ash with aluminium as matrix with volume percentage varying from 0 to 16 percent. The dispersion of the Fly Ash particle was uniform in the stir zone irrespective of the location and thus improved mechanical properties were obtained.…”

The present study aims to investigate the Aluminium oxide and Zirconium diboride particles reinforced aluminum surface composites fabricated using Friction Stir Processing (FSP). Al-6063 was used as base-metal and Aluminium oxide and Zirconium diboride were used as reinforcement media. Al 6063 is used for architectural fabrication; window and door frames, pipe and tubing, and aluminium furniture Tensile strength specimens were prepared as per ASTM –E8 Standard. Tensile strength were found using UTM. Then it is found that that the tensile strength of the composite decreases as the volume percentage of the particles added for the reinforcement increases in the composites.
