Summary: This study systematically investigates the microstructure and high temperature mechanical properties of Mg-10Gd-3Y-xNd-0.5Zr alloy. It is found that Nd element promotes the precipitation phase and forms a new phase Mg41Nd5, while the appropriate amount of Nd refines the grain size. The Mg-10Gd-3Y-xNd-0.5Zr alloy exhibits excellent mechanical properties at both room and high temperatures, with significant ultimate tensile strengths. The main strengthening phases are p phase, p' phase, and 18-LPSO phase. Moreover, the alloy shows excellent high-temperature creep resistance and the creep mechanism changes with temperature and stress.

Summary: The effects of isothermal multi-directional forging (MDF) on the microstructure, texture evolution, and mechanical properties of homogenized Mg-13Gd-4Y-2Zn-0.5Zr alloy were investigated in this study. The results showed that the MDF passes gradually decreased the average grain size of the alloy, resulting in a more uniform microstructure distribution. The MDF process also led to changes in the distribution of LPSO phases and Mg5(Gd,Y) precipitates within the grains. Additionally, the maximum texture intensity on the basal plane decreased with the increasing MDF passes due to the formation of dynamic recrystallized grains. The alloy exhibited excellent mechanical properties, attributed to various strengthening mechanisms such as grain boundary strengthening, dislocation strengthening, texture strengthening, and precipitation strengthening.

Summary: This study investigated the effect of extrusion parameters on the microstructural evolution and tensile properties of a Mg-8.0Gd-4.0Y-1.0Mn-0.4Sc alloy. Different DRX mechanisms, such as DDRX and CDRX, were identified, and the alloy with larger extrusion ratio exhibited smaller DRXed grains and a high number of fine precipitated particles. The alloy extruded at 400°C and ratio of 20:1 showed superior strength, while alloy extruded at 450°C and ratio of 10:1 exhibited higher elongation to failure. The enhanced strength was attributed to strong basal texture, refined DRXed grains, and dense distribution of fine particles.
