“…The grain structure in the HAZ of the S66 weld (Fig. 7a) is similar to that of the unaffected base material and no hardness decrease was observed in this zone, such as reported by several authors for other alloys of the 6xxx series [3,19,26,31,32]. This can be attributable to the low heat input during the weld process.…”

a b s t r a c tThe tensile behaviour of similar and dissimilar friction stir welds in 1 mm thick sheets of two aluminium alloys (AA5182-H111 and AA6016-T4) is analysed in this paper. The heterogeneity in properties across the welds was studied by performing microhardness tests and microstructural analysis. The tensile tests were performed in samples extracted longitudinal and transverse to the weld direction. It was found that the tensile behaviour of the welds depends mainly on the grain size in the TMAZ, for the AA5182-H111 alloy, and on precipitate distribution, for the AA6016-T4 alloy. In all types of welds, the HAZ preserves the same properties of the base materials. The global mechanical behaviour of the AA5182-H111 similar welds is very similar to that of the base material. However, for the AA6016-T4 similar welds and for the AA6016-T4-AA5182-H111 dissimilar welds a 10-20% strength reduction relative to the base materials and important losses in ductility were reported.

“…In [35] and [1] an attempt is made to derive the microstructure from the chemical composition and the thermal history of the alloy. In [1] a complete model for this is proposed, which combines a precipitation model and dislocation based initial yield strength and work-hardening models for the 6xxx family of alloys.…”

“…6,7) In particular, the FSW of materials with lower melting points, such as Mg and Al alloys, has been carried out often. [8][9][10] However, the FSW of Ni-based super-alloys has been rarely carried out because of their high strength even at high temperatures. Only Inconel 600 has been reported to be friction stir welded; albeit, at a lower welding speed.…”

The present study was carried out to evaluate the microstructural and mechanical properties on friction stir welded Inconel 625 alloy. For this work, friction stir welding was performed at a tool rotation speed of 200 rpm and a traveling speed of 100 mm/min. As a result, the grain refinement was achieved from 10.3 mm in the base material to 2.1 mm in the stir zone at an average grain size, accompanied by the dynamic recrystallization. This grain refinement has an effect on the increase of mechanical properties so that microhardness and tensile strength were significantly increased than that of the base material, more than 40% and 15% in fraction, respectively.
