Summary: In-plane shear deformation is introduced into the pre-twinned AZ31 Mg alloy sheet to modify the basal texture and improve the formability. The twinning orientation is secondary regulated and rotated away from the transverse direction, resulting in a significant weakening of the basal texture. After annealing, the recrystallized grains inherit the grain orientation of rotating twins, leading to improved fracture elongation and Erichsen value.

Summary: The microstructure and mechanical properties of a 90% cold-rolled AlCoCrFeNi2.1 eutectic high-entropy alloy undergo changes during annealing at 800 degrees C. Recrystallization occurs faster in the FCC phase compared to the B2 regions, resulting in increased grain size. Partially recrystallized samples produced by annealing exhibit a combination of high yield strength and good ductility.

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.

Summary: Powder metallurgy Cu-30Fe alloy was prepared using mechanical alloying, pressureless sintering, and rolling processes. The rolling process affected the alloy microstructure and physical properties. The Fe particles became elongated and changed shape, while the Cu grains became elongated and refined. The coordinated deformation of the Cu and Fe phases resulted in finer Cu grains near the Fe particles. After annealing, the cold-rolled Cu-30Fe alloy achieved a good combination of mechanical and functional properties.

Summary: The microstructure, crystallographic texture, and tensile properties of a CoCrFeNi medium entropy alloy were studied after cold rolling and annealing. It was found that shear bands and layers of mixed orientations act as preferential nucleation sites for recrystallized grains during annealing. High mechanical strength and good ductility were obtained in samples annealed at 550°C or 570°C, attributed to a fine-scale bimodal microstructure.

Summary: The WE43 sheets were prepared by single-passed rolling at 370°C and 450°C with total reductions of 40% and 50%, and the microstructure and mechanical properties were compared. Both the R370-40% and R450-50% alloys showed non-recrystallized structures with high-density dislocations and strong basal texture. Compression twins and double twins were formed at 370°C, while tensile twins were formed at 450°C. The R370-40% alloy had lower ductility, while the R450-50% alloy had higher ductility. The low plasticity of the R370-40% alloy was mainly attributed to the activity of compression twins and double twins.

Summary: This study investigates the accumulated extrusion bonding (AEB) of AZ31 Mg alloy with a heterogeneous bimodal grain structure. The combination of local water cooling and artificial cooling during the process results in the consecutive development of the microstructure through discontinuous dynamic recrystallization (DDRX). The two-stage cooling approach enables the retention of fine DRXed grains and high-residual dislocation density unDRXed grains, leading to a good strength-ductility balance.
