Summary: The influence of trace Si on the microstructure and corrosion behavior of as-cast Mg-0.4Mn-xSi alloys has been studied. It was found that the presence of trace Si leads to the formation of MnSi, Mn5Si3, and Mn3Si phases, thereby significantly increasing the corrosion rate of the alloys. During corrosion, rod-like MnxSiy precipitates exhibit stronger cathodic activation behavior compared to block-like precipitates.

Summary: The effects of different Al contents on the microstructure, extrusion texture, and corrosion behavior of dilute Mg-Al-Ca-Mn alloy were studied. The corrosion rate of the alloy was found to be more sensitive to Fe impurities. The lowest corrosion rate was observed in the alloy with 1.2 wt% Al, which was mainly attributed to the weakening of the cathode effect caused by the increase of Al and the decrease of Fe in the precipitated phase. Refined grains, stronger basal surface texture, and higher corrosion potential from the higher Al content of the matrix further enhanced the corrosion resistance of the alloy.

Summary: The corrosion resistance of Mg-Mn alloy primarily depends on the solubility of iron in the magnesium matrix, and suitable manganese addition can significantly reduce corrosion. The tolerance limit of iron impurity is expressed as Fe-max = 0.0083 Mn, and only when the Fe/Mn ratio is below 0.0083, the alloy can exhibit excellent corrosion resistance.

Summary: This study investigates the biodegradation properties of pure magnesium with different iron contents and surprisingly finds that the iron impurity does not have a negative effect on the degradation of pure magnesium, even when the iron content exceeds the previous tolerance limit. Detailed microstructural analyses reveal that the severe local micro-galvanic corrosion caused by the iron impurity promotes the formation of a compact calcium-rich corrosion product layer, protecting the adjacent magnesium matrix from further corrosion.

Summary: Lean Mg-1.2Zn-0.3Ca-0.3Al-xMn (x = 0.25, 0.38, 0.5 wt%) alloys with different Al/Mn ratios were prepared using twin-roll casting technique. The formation of rhombohedral Al8Mn5 or cubic beta-Mn depended on the Al/Mn ratio. The alloy with Al/Mn>1.6 exhibited the lowest average corrosion rate (4.55 mm y-1) due to the lower Volta potential of Al8Mn5 compared to beta-Mn. The presence of fine Al8Mn5 weakened micro-galvanic corrosion and reduced stress concentration, resulting in admirable corrosion resistance and mechanical properties (UTS: -266 MPa, YS: -193 MPa, EF: -20%) for the alloy with Al/Mn>1.6.

Summary: The role of Si in the mechanism of intergranular corrosion (IGC) in Al-Mn-Fe-Mg-Cu alloy is still unclear. The microstructure at the grain boundaries of the alloy was characterized by high resolution transmission electron microscopy (HRTEM). The presence of Si layer, discrete Al4Cu2Mg8Si7 and alpha-Al(Fe,Mn)Si precipitates along the grain boundary, as well as the precipitation-free zone (PFZ) adjacent to the grain boundary, contribute to IGC.

Summary: This article investigates the difference in corrosion behavior between transverse and longitudinal sections of hot-extruded Mg alloys containing long period stacking ordered (LPSO) phase. Increasing the ram speed can enhance the basal texture and improve the corrosion resistance. Larger dynamically recrystallized (DRXed) grains with a higher volume fraction and finer scaled LPSO strips are beneficial to the corrosion properties.

Summary: A Fe-Mn-Pd alloy with an ultrafine-grained structure was produced by equal channel angular pressing (ECAP) at temperatures of 300 degrees C and 450 degrees C. ECAP significantly increased the strength of the alloy while maintaining satisfactory plasticity. The corrosion rate of the alloy was higher after ECAP compared to the coarse-grained state and annealed iron. However, ECAP did not impair the biocompatibility of the Fe-Mn-Pd alloy and the colonization of the sample surface by cells.

Summary: The effects of adding different amounts of AlN nanoparticles on the microstructural evolution and strengthening mechanisms of Mg-3Sn-1Ca based alloys were investigated. It was observed that increasing the amount of AlN nanoparticles led to a significant decrease in grain size. The presence of AlN nanoparticles refined the primary crystal phases and provided more nucleation sites for the formation of magnesium. Additionally, the nanoparticles restricted grain growth during solidification. The addition of AlN nanoparticles resulted in improved tensile properties and hardness at both room temperature and high temperature.

Summary: The addition of rare earth element Y can effectively improve the creep properties of magnesium alloys, enhancing both ambient strength and high temperature strength. Y additions exhibit a linear relationship with the yield strength of Mg-Y alloys at room temperature, but reduce the yield strength at high temperatures. These alloys also demonstrate high thermal stability above 200 degrees C. The creep resistance of magnesium is largely improved with small amounts of Y, but further increasing Y content weakens its contribution to creep resistance.

Summary: The influence of different Al contents on the microstructural evolution and creep resistance of Mg2.85Nd-0.92Gd-0.41Zr-0.29Zn alloy was investigated. It was found that the additions of 0.5 wt% and 1 wt% Al significantly decreased the creep rate, while the addition of 2 wt% Al led to decreased creep properties. Microstructural analysis revealed changes in grain coarsening or refinement and phase transformation with different Al contents. Creep resistance was enhanced by the additions of 0.5 wt% and 1 wt% Al, but deteriorated by the addition of 2 wt% Al due to the detrimental microstructure.

Summary: This study proposes a new antibacterial mechanism, showing that the antibacterial effectiveness of alloys is proportional to the micro-area potential differences on their surface. By designing different alloys to eliminate the antibacterial contribution of copper and silver ions, it was found that high micro-area potential differences lead to the production of reactive oxygen species, resulting in antibacterial effects.

Summary: This study further improved the mechanical properties and thermal conductivity of Mg-Zn-La/Ce alloys through aging treatment, achieving good comprehensive performance. The addition of La/Ce forms a ternary tau 1 phase that reduces the supersaturation of the Mg matrix and has a positive effect on thermal conductivity. Precipitation has two opposite effects on thermal conductivity, reducing supersaturation but hindering the free movement of electrons and phonons.

Summary: Heterogeneous TiC/AZ61 nanocomposites were fabricated to enhance both the strength and ductility of Mg matrix composites. The proportion of TiC-rich fine grain (FG) zones and TiC-rare coarse grain (CG) bands could be adjusted by changing the mechanical ball milling time. The composites achieved excellent mechanical properties with a volume fraction of 25% CG bands after 20 h of ball milling, which was attributed to the presence of geometrically necessary dislocations (GNDs) in the CG bands.

Summary: This study investigates the creep behavior and microstructural evolution of sand-cast Mg-14Gd-0.4Zr alloy using compressive creep tests. The results show that the coherent distribution of beta' and beta' (F) phases effectively impedes dislocation movement and enhances creep resistance. However, with increasing creep time, the fine precipitate chains coarsen and transform into different phases, leading to stress concentration and increased creep strain.
