“…Hence, we only need to consider symmetric GBs. Additionally, alloying elements affect GBE if they are segregated at GBs, but the 30°misorientation have been observed irrespective of alloy type and composition [5][6][7][8][9][10][11][12][13][14][15][16], so our CSL analysis of pure Mg should be legitimate for Mg alloys, and we focused our simulations on the 30°misorientation.

“…After thermomechanical processing of Mg alloys, a particular type of grain boundaries (GBs), i.e. 30°[0 0 0 1] misorientation has been repeatedly observed with an intensity peak in the distribution of the misorientation angle [5][6][7][8][9][10][11][12][13][14][15][16] in dynamically recrystallized microstructures of Mg and Mg alloys. This type of GBs appears to be common in HCP metals, for example, it was also observed in Zr [17].…”

“…Mukai et al [61] reported the properties of the WE43 alloys in annealed, extruded and aged conditions and reported that the extruded alloy exhibits superior properties in terms of strength and ductility due to the fine grained microstructure and transition from intergranular to transgranular fracture with grain refinement. Panigrahi et al [62] studied the effects of forging and ageing on the mechanical properties of WE43 alloys and reported that the improvement in strength is due to the combined effect of grain refinement, work hardening and precipitation strengthening. The improvement in ductility is also reported to be due to the limited intergranular fracture and activation of non-basal slip prior to twinning.…”

Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the previously investigated different magnesium-rare earth based binary alloys, ternary alloys and other higher alloys with more than three alloying elements are presented.

“…In terms of corrosion behavior, it has been observed that the basal plane possesses higher general corrosion resistance (unstressed) in HCP materials in comparison to other planes [33,34]. Moreover, the grain refinement achieved through FSP of magnesium alloys can alter the deformation behavior by suppressing the twinning and activation of non-basal slip [35,36]. The conditions leading to activation of hc ?…”

In this study, stress corrosion cracking (SCC) behavior of AZ31 magnesium alloy was carried out using slow strain rate testing (SSRT) technique in 3.5 wt% NaCl solution. The influence of microstructural scale on the stress corrosion behavior was investigated in AZ31 alloy with three different mean grain sizes. Single-pass and two-pass friction stir processing (FSP) was employed to obtain fine grain and ultrafine grain microstructures, respectively. For FSP, SSRT specimens were extracted from the processed region. SSRTs were carried out in air and solution at an initial strain rate of 10 -6 /s. A significant decrease in the ultimate tensile strength was observed for FSP specimens tested in chloride solution as compared to specimens tested in air. More than 75 % loss in total elongation was observed for the specimens tested in chloride solution as compared to the ones tested in air. In comparison with base material, lower time to failure was observed for processed samples. The higher SCC susceptibility of processed microstructure is attributed to increased hydrogen adsorption and favorable basal texture.
