Summary: In this study, the static recrystallization behavior and basal texture change of the cold-rolled AZXW1100 alloy during annealing were investigated. Highly deformed shear bands were observed in the cold-rolled alloy sheet, which caused rapid recrystallization at the beginning of annealing. The recrystallized grains nucleated in the shear bands guided the overall recrystallization behavior and led to the formation of a diamond-like or TD-split texture.

Summary: An ultrahigh strain-independent damping in Mg-1Mn alloy was achieved by the cold rolling process. The introduction of non-basal dislocations and stacking faults through cold rolling improved the strength, plasticity, and damping capacity of the alloy. The increase in moveable dislocations and stacking faults effectively enhanced the alloy's damping capacity. This work presents a new strategy for developing high-strength, high-plasticity, and high-damping magnesium alloys.

Summary: The study investigated the texture evolution of a Mg-Zn-Ca plate during cold rolling and subsequent annealing. It was found that basal slip was the main deformation mode and prismatic slip preserved the TD-split texture. Pyramidal slip caused the widening of the basal texture. Grain nucleation occurred at grain boundaries, deformation twins, and near precipitates, with minimal texture change.

Summary: After cold-rolling an Mg-6Zn-0.3Ca alloy sheet with a strong basal texture, anomalous double twinning occurred with the (0001) pole aligned to the transverse direction. These twins served as nucleation sites for statically recrystallized grains during annealing, resulting in weak texture features in the annealed sheet with transverse-direction split (0001) poles.

Summary: The thermal decomposition behavior of Bayan Obo mixed rare earth concentrate (BOMREC) under nitrogen atmosphere was studied to provide fundamental research for advanced technology in its metallurgy. The results showed that during roasting at 500-550 degrees C, there was approximately 10% mass loss and an activation energy of 148 kJ/mol. After roasting at 550 degrees C for 2 hours, bastnaesite in BOMREC completely decomposed into rare earth oxides and fluorine oxides, with a maximum cerium oxidation efficiency of 0.58% and a maximum leaching efficiency of REEs at 49.1% after thermal decomposition at 600 degrees C for 2 hours.

Summary: This paper reports the application of cold-sample rolling (CSR) processing in a Mg-6Al-1Zn alloy sheet, which resulted in a high fraction of double twins and a substantial texture-weakening effect. Compared to high-temperature rolling (HTR) processing, CSR processing induced a relatively higher texture-weakening effect. The results indicate that twinning-mediated static recrystallization is essential for texture weakening in Al-concentrated Mg-alloy sheets.

Summary: The microstructure evolution and thermal stability of nanocrystalline AZ31-2.5 wt%VP magnesium matrix composites were investigated. The findings revealed that the composite maintained a nanocrystalline scale even after annealing at high temperatures, indicating excellent thermal stability. The uniformly distributed V particles in the magnesium matrix effectively inhibited grain growth and no new phases were formed. The hardness of the composite remained high even after annealing treatment.

Summary: This paper investigates the corrosion behavior of Mg-5.7Gd-1.9Ag alloy sheets in a salt solution. The results show that the rolled sheets exhibit better corrosion resistance compared to the as-cast sheets. Aging treatment decreases corrosion resistance, but it still remains higher than that of the as-cast sheets. The migration of corrosion is mainly influenced by the evolution of second phases rather than grain size and texture.

Summary: In cold-rolled specimens, fine equiaxial grains with highly oriented gradients are often found around coarse precipitates, which are considered as recrystallization nucleation sites under cold rolling. By solving the inhomogeneity problem using Eshelby tensors under cold rolling conditions, it is observed that stress and strain disturbances around the precipitate vary substantially with the aspect ratio of the precipitate. The predictions of residual stress suggest that the formation of a rotated zone is caused by the relaxation of disturbed stress during cold rolling.

Summary: In recent studies, it was found that high energy ball milling of Mg/MgH2 mixed with additives can reduce the temperature for H-2 absorption/desorption without altering thermodynamic properties. This research aimed to identify efficient hydrogen absorption/desorption catalysts at low temperatures, particularly at room temperature (RT). Among the additives tested in this study, MgH2-TiFe mixture showed the best performance, attributed to the strong catalytic action of TiFe and the high energy interfaces attracting hydrogen gas.

Summary: The crystal structure and hydrogen storage properties of a new equiatomic TiZrNbCrFeNi high-entropy alloy (HEA) were investigated. The alloy exhibited an AB-type configuration, selected through thermodynamic calculations and showed the ability to absorb 1.5 wt% of hydrogen at room temperature without activation. Cyclical testing revealed changes in the fractions of two C14 Laves phases, with one phase having higher reactivity towards hydrogen. The alloy exhibited a single C14 Laves phase after dehydrogenation at 473 K, and microstructural analysis showed excellent homogeneity and element distribution.

Summary: Hydrogen storage properties of magnesium alloys were investigated after processing with different methods. The results showed that the ECAP + LTR route led to a more refined microstructure and improved resistance to oxidation and/or hydroxide formation. The samples processed by ECAP + LTR exhibited faster activation kinetics due to the presence of highly oriented grains and a large number of defects.
