“…The BM has larger ‘Macrozones’ than the HAZ, the HAZ of EFSW joints has smaller ‘Macrozones’ than that of the FSW joints, the SZs of FSW joints and EFSW joints contain almost no macrozones. The macrozones, also known as microtextures, are composed of grains with similar orientations [1], this meant that the BM and the HAZ of the FSW joint and the 100A-EFSW joint have the strong {10 0} prismatic texture linked to prismatic slip [22,36], leading to the soft oriented large macrozone grains in the BM. Lunt [22] reported that the deformation by a prismatic slip in the soft oriented macrozone grains was much stronger than the grains without macrozones, the maximum shear in the strong macrozone material was considerably higher than the values for the non-macrozone condition.…”

Microstructure, texture and mechanical properties of electrically assisted friction stir welding (EFSW) of Ti6Al4 V alloy were investigated. The base material (BM) and the heat-affected zone (HAZ) have a coarse equiaxed structure, and the fine equiaxed structure was observed in the stir zone (SZ). The boundary between the SZ and the HAZ changed abruptly from the FSW joint to the EFSW joint to make it smooth. The BM and the HAZ have a strong prismatic texture {10[Formula: see text] 0} and the texture of the SZ is randomly distributed. Hardness of the joints was explained by grain size, loss rate of elemental Al and dislocation density, as well as the advantages of the EFSW process in terms of improving mechanical properties as influenced by microstructure and texture.
