“…The texture influences the strength of HCP polycrystals through its effect on the Hall-Petch constants. 17 Similarly, Yuan et al 18 have reported that the coefficient of the Hall-Petch equation was proportional with texture intensity, i.e., stronger textures led to higher strength in Mg alloys, while Xin et al 19 indicated that the strong and complicated textures formed in Mg alloys caused strong anisotropy in the mechanical properties. In addition, previous studies have found that the addition of alloying elements and presence of precipitate particles can influence texture evolution during hot deformation.…”

A "RE-free" and I-phase-containing Mg-8Sn-based alloy system was developed and successfully fabricated through the equal channel angular pressing (ECAP) process. The influence of the Zn/Al mass ratio on the microstructures and mechanical properties of the as-ECAPed Mg-8Sn-(5,6,7) Zn-2(wt%)Al alloys was investigated using an optical microscope, an X-ray diffractometer, a scanning electron microscope, a transmission electron microscope, and a universal testing machine. Grain size, dynamic recrystallization behavior, and texture were found to be greatly affected by the Zn/Al mass ratio. Furthermore, the ultimate tensile strength (250 MPa) and elongation (14.5%) of the alloy with a Zn/Al mass ratio of 3 were considerably increased compared to those of the as-ECAPed alloys with Zn/Al ratios of 2.5 and 3.5 (ultimate tensile strength and elongation of 215 MPa and 13% and 184 MPa and 10%, respectively). This significant enhancement was attributed to extensive grain boundary strengthening, precipitation strengthening, and higher work hardening capacity as well as texture randomization. The strength and ductility of the as-ECAPed alloys are also discussed in terms of the I-phase and Mg 2 Sn formation.

“…The dynamic recrystallization (DRX) processes are divided into continuous dynamic recrystallization (CDRX) and discontinuous dynamic recrystallization (DDRX). The key distinguishing feature is that the obvious bulging of original grain boundaries could be observed during DDRX [10]. It can be seen that the bulging of original grain boundaries is observed from Fig.…”

Systematic experimental studies on microstructure evolution and texture development of pure Al during torsion at room temperature are carried out by electron back scattering diffraction (EBSD) and transmission electron microscopy (TEM). The microstructure evolution states the grains of deformed pure Al are refined evidently. The refinement mechanisms of pure Al are attributed to dislocation slip and recrystallization. The texture evolution of pure Al indicates that the position of {001} fiber changes slightly, but its intensity first increases and then decreases with the increase of deformation during torsion. Finally, the processes of grain refinement of pure Al during torsion are discussed based on TEM observations.

There is an increase in reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest will lead towards using dissimilar aluminium alloys which will require welding. Currently, tungsten inert gas welding and friction stir welding are the well-known techniques suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the welds of dissimilar alloys post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of a material. This paper reports on the status and the advancement of friction stir welding, tungsten inert gas welding and the friction stir processing technique. It further looks at the variation use of friction stir processing on tungsten inert gas and friction stir welded joints with the purpose of identifying the knowledge gap.
