Microstructure and Texture Evolution of Hot-Rolled Mg-3Gd Alloy during Recrystallization

“…For the regions with ε > 0.20, the weak recrystallization texture was maintained and its intensity value decreased with increasing annealing time due to the increase in recrystallized grains. It is well known that the recrystallized grains always nucleate at DTWs and CTWs in the deformation twins-dominated regions [9], while the recrystallized grains nucleate inside shear bands in the shear bands-dominated regions [8]. However, the weak recrystallization texture was formed in almost the entire strain range, indicating that both deformation twins-related and shear bands-related recrystallization led to the weak recrystallization textures.…”

However, the weak recrystallization ture was formed in almost the entire strain range, indicating that both deformation tw related and shear bands-related recrystallization led to the weak recrystallization textu To gain a better understanding of the effect of the orientation distribution of the crystallized grains in the deformation twins-dominated and shear bands-domina structures on the final recrystallization textures, the texture of all recrystallized grain divided into two texture components with orientation deviating ±0-20° and ±20-90° fr ND towards RD, respectively.…”

“…Interestingly, the addition of rare-earth (RE) elements, e.g., Y, Gd, Ce, La and Nd, in Mg alloys can highly decrease the intensity of basal textures, anisotropy, and asymmetry, owing to the formation of a weak texture component during recrystallization [5][6][7]. It is well known that shear bands [8], twin boundaries [9], and particles [10] are the preferential recrystallization nucleation sites for enhancing the formation of a weak recrystallization texture in Mg-RE alloys [11,12]. Meanwhile, the recrystallization behavior of Mg alloys is also highly dependent on the degree of strain [13,14].…”
