Microstructure and texture of coarse-grained Mg–Gd–Y–Nd–Zr alloy after hot compression

Dynamic recrystallization behaviors and the resultant mechanical properties of a Mg–Y–Nd–Zr alloy during hot compression after aging

“…Fine precipitates appear only in the region of DRX grains, in contrast, they hardly exist in a remained coarse grain, which suggests that dynamic precipitation may frequently take place accompanying with grain refinement. The similar phenomenon was observed in the compression experiment of Mg-Gd-Y-Nd-Zr alloy [17]. Fig.…”

Effect of compression conditions on the microstructure and texture of a Mg–RE alloy

“…Although the extra-fine grains present the similar orientations of grains of sample B or C, the unpinning effect in the extra-large grains gives rise to an apparent basal texture of sample D. This founding suggests that it is the RE-rich particles rather than the high concentration of RE elements in the matrix are necessarily required for the texture randomization and weakening during hot compression of the studied alloy, which is consistent with some previous results. A higher area fraction of particles ensured weaker deformation textures and made the deformed texture retained after the further deformations [3,24,25], or else, some common deformation textures as those in the conventional Mg alloys can be evolved, such as the ideal basal texture after compressions in AZ series alloys [26].…”

Optimum parameters and kinetic analysis for hot working of a homogenized Mg–8Sn–1Al–1Zn alloy

“…It is generally accepted that magnesium alloys have poor workability at room temperature, caused by insufficient slip system of the hexagonal close-packed (HCP) structure [1,2]. Recently, the Mg-Sn alloy has been a promising area of research for high-performance casting and wrought magnesium alloys due to the presence of the high thermal stable Mg 2 Sn phase (T m = 770°C) , which is comparable to RE-containing precipitates (T m = 500-750°C) in the Mg-RE system (RE stands for rare earth elements) [3].…”
