Amounts of segregation at grain boundaries of Mg-0.05at％X (X = Al, Bi, Ca, Ce, Gd, Nd, Y, Zn, Zr) alloys were calculated by using the Hillert's grain boundary phase model. As a result, relatively high grain boundary segregation was obtained in each case of Ca, Ce, Nd, Y and Zn. In addition, the basal plane texture and Erichsen value of the alloys were experimentally investigated, which exhibits a similar tendency to the previous experiments, i.e., the Erichsen value decreases with decreasing basal texture intensity. High-angle annular dark-field STEM (HAADF-STEM) analysis of the Mg-0.4Nd (mass％) and Mg-0.2Y (mass％) sheets elucidated that the uniform grain boundary segregation was detected in Mg-0.4Nd, while the localized and scattered segregation region was observed at grain boundary in Mg-0.2Y. These segregation behaviors were explained by the concept of critical element concentration proposed by Griffiths. An un-recrystallized grain microstructure with high lattice distortion was observed in Mg-0.4Nd in Scanning Electron Microscope -Electron Back-Scatter Diffraction (SEM-EBSD) analysis, which leads to a possibility that the grain boundary segregation of Nd contributes to the suppression of recrystallization during rolling. As the strong correlation was observed between the calculated grain boundary segregation and the experimental basal texture intensity, the amount of grain boundary segregation is a useful parameter for describing basal texture intensity of binary Mg alloys.

“…Magnesium alloys have high speci c strength, high speci c stiffness, good electrical conductivity and excellent processing properties [1][2][3][4] and are widely used in aerospace and communication equipment [5][6]. However, magnesium alloys have poor plasticity at room temperature due to their unique dense hexagonal (HCP) crystal structure [7][8].…”

In this study, a tube extrusion-shear-expand (TESE) process is proposed for the preparation of thin-walled tubes of high-performance magnesium alloys, and a comparison with direct extrusion(DE) is used to verify the superiority of the new process. Numerical simulations of the mesh variation, forming load, and equivalent strain during the forming of magnesium alloy tubes were carried out in combination with DEFORM-3D software. The results of the study show that: under the TESE process, the equivalent strain and the forming load are larger, which makes the plastic deformation of the tube larger; the grain re nement effect of the tube prepared under the TESE process is more obvious than that of the DE; the yield strength of the tube under the TESE process is about 293MPa, the elongation is about 15%, and the base structure dispersion is higher under the dynamic recrystallization and larger shear effect, the strength is obviously weakened, and the comprehensive performance of magnesium alloy tube is improved.
