Summary: Zn-0.2 Mg-(0.1-0.8)Mn alloys were prepared by indirect extrusion at 200 °C. The addition of Mn resulted in an increase in MnZn13 content, which contributed to the increase in tensile strength and decrease in elongation. Meanwhile, the non-basal texture also played a role in determining the alloy properties.

Summary: A Zn-2Cu-0.1Ti (ZCT) alloy was fabricated using a combination of casting and hot-rolling. X-ray diffraction analysis revealed the presence of TiZn16 and CuZn4 phases in the alloy. The ZCT alloy exhibited a significantly higher yield strength compared to pure zinc, as well as similar elongation to failure. Additionally, the alloy had a lower corrosion rate in simulated body fluid and showed excellent biocompatibility for MC3T3-E1 cells, indicating its potential for clinical applications.

Summary: Ultrahigh-strength Mg-9.2Gd-4.4Y-1.0Zn-0.8Mn (wt%) alloys were produced through isothermal ageing, resulting in a microstructure characterized by bimodal a-Mg grains and prismatic b' and basal g' phases precipitated during ageing. The peak-aged alloys exhibited the highest tensile strength, with satisfactory ductility, due to dense number distribution co-precipitation that increased critical resolved shear stresses and inhibited microcrack nucleation and propagation. These findings have significant implications for high-strength Mg-Gd-Y-Zn alloys in practical applications.

Summary: A high-strength Mg-8.8Gd-3.8Y-1.0Zn-0.7Mn alloy hollow profile with complex cross-section was successfully fabricated through porthole die extrusion, and the microstructure and element distribution of its weld seam were analyzed to investigate the impact of solid-state bonding. The weld seam displayed a homogeneous magnesium grain structure and a precipitation-free zone. The diffusion behavior of alloying elements significantly affected the microstructure of the weld seam, with Gd and Y atoms diffusing towards the outside of the weld region. The hollow profile exhibited favorable mechanical properties, with a minor negative effect from the weld seam.

Summary: In this study, novel Mg-1Bi-xMn (x = 0, 1, and 2 wt.%) extruded alloys were fabricated at different extrusion temperatures. The effects of extrusion temperature and Mn addition on the microstructures and mechanical properties of extruded alloys were investigated. The results showed that decreasing the extrusion temperature refined the grain size and improved the microstructural homogeneity, while adding Mn further reduced the grain size and impeded grain boundary migration for grain refinement. The control of alloy composition and extrusion temperature can achieve a balance between mechanical properties and deformability.

Summary: In this study, a Mg alloy with alloying elements of Zn, Al, Sn, and Mn was designed, and hot extrusion was carried out at various speeds and temperatures. It was found that high speed extrusion resulted in more second phase particles, while high extrusion temperature increased the number of second phases, grain size, and dynamic recrystallization degree. The sample extruded at a speed of 10 mm/min and temperature of 300 degrees C showed the highest yield strength, tensile strength, and corrosion resistance.

Summary: Indirectly extruded Zn-0.2Mg-(0, 0.05, 0.2, 0.4 wt%)Fe alloy rods exhibited improved ductility without sacrificing strength with the addition of minor Fe. The texture variation and grain refinement contributed to the enhancement of ductility and slight increase in strength. Increasing Fe content from 0.05 wt% to 0.4 wt% resulted in a reduction in elongation while maintaining yield strength and ultimate tensile strength.

Summary: The study found that increasing the manganese content can significantly enhance the yield strength of Mg-3Zn-0.5Ca-0.5Al-xMn alloy, but further increasing to 1.5 wt% manganese content does not contribute to further strengthening. However, the alloy with 1 wt% manganese added achieved high strength, high formability, and improved thermal conductivity.

Summary: Zn-based alloys are a potential biodegradable implanted biomaterial. The study found that Zn0.8Mn0.1Li alloys have significantly improved degradation property and cytocompatibility, but have adverse effects on the surface morphology of osteoblasts. However, the biocompatibility of Zn0.8Mn and Zn0.8Mn0.1Li alloys scaffolds can be enhanced by CaP coating.

Summary: Zn-Mn alloy coatings formed by electrodeposition have been found to improve the corrosion resistance of Mg substrates, while also increasing the hardness, wear resistance, and coefficient of friction of the coatings. The composition of the alloy influences the phase formation, with higher manganese content favoring the formation of the z-MnZn13 phase. By varying the manganese content, the microhardness, wear volume, and degradation rate of the coatings can be modulated.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
