Summary: The effect of Gd content on the microstructure and tensile properties of as-cast Mg-Sm-Zn-Zr alloy was investigated. The addition of Gd inhibited the segregation behavior of Zn in the Mg3Sm phase and improved the tensile yield stress of the alloy. Gd-modified alloys exhibited significant age-hardening effect, attributed to the high-volume fraction and high density nano-scale precipitates.

Summary: The effects of glucose on the mechanical safety and cytotoxicity of Mg alloys used as implant materials are studied. Under high-glucose conditions, Mg alloys may experience decreased mechanical properties and corrosion fatigue failure. Higher glucose content in Hank's solution results in enhanced corrosion resistance and improved corrosion fatigue. The Mg-Zn-Zr-Y alloy shows excellent cytocompatibility under high-glucose conditions during in vitro tests.

Summary: Mg-6.75Zn-0.57Zr-0.4Y-0.18Gd (wt.%) sheet with typical basal texture was produced by cross rolling and annealing. The deformation mechanism and orientation evolution during tension were studied, and the results showed that the activation of deformation mechanism depended on the initial grain orientation. Different grain orientations exhibited different deformation modes and lattice rotation behavior, which influenced the mechanical properties of the material.

Summary: A high-performance Mg-10Gd-4Dy-1.5Ag-1Zn-0.5Zr (wt.%, EQ142X) alloy was designed using multi-element composite addition, resulting in high yield strength (approx. 396 MPa) and ultimate tensile strength (approx. 451 MPa) after hot extrusion and ageing. The high strength is attributed to fine grains and nano-precipitates, especially beta' and gamma nano-precipitates, which act as the main strengthening phases. The introduction of nano-precipitates network into the fine-grained structure is proposed as an effective strategy for developing high-strength Mg alloys.

Summary: The microstructures and mechanical properties of Mg-8.5Gd-4.5Y-0.3Zr alloys with and without Zn addition were investigated in this study, and the strengthening mechanisms of these two alloys were also discussed. The results show that the as-extruded alloy with Zn addition has finer grains due to the inhibited dislocation motion. Dynamic precipitation occurs during the extrusion process and unevenly distributes in both alloys, promoting grain refinement. The alloy with Zn addition exhibits significantly higher yield strength and elongation compared to the alloy without Zn addition, mainly attributed to the strengthening effects of the LPSO and g0 phases.

Summary: The combined effects of LPSO orientation and alpha-Mg texture on tensile anisotropy were investigated, with the extrusion direction showing optimal mechanical properties, the 45 degrees direction exhibiting high elongation, and the transverse direction having inferior strength and elongation simultaneously. LPSO orientation contributes to strength anisotropy through different load-bearing strengthening effects along different tensile axes, while alpha-Mg texture contributes to strength anisotropy through stronger grain boundary strengthening effects. However, LPSO orientation, rather than alpha-Mg texture, accounts for ductility anisotropy.

Summary: The effects of RE additions on the biodegradability of Mg-Zn alloys were studied, and it was found that the size and distribution of precipitates played a significant role in corrosion response. The EZ33 alloy exhibited better corrosion resistance and biocompatibility, while the ZE41 alloy showed more severe degradation and reduced mechanical properties.

Summary: The use of cerium-based conversion coating has been shown to effectively improve the corrosion resistance of squeeze-cast Mg-4wt%Y alloy in a salt solution, with significant reduction in corrosion rate observed compared to the base alloy. The corrosion mechanism predominantly involves pitting corrosion around the second phase due to micro-galvanic coupling between alpha-Mg phase and Mg24Y5 precipitates.

Summary: The aim of this study is to investigate the effect of heat treatment on the microstructure, mechanical, and corrosion properties of Al 319.0 alloy. The results show that heat treatment leads to the dissolution of certain phases and changes in the morphology of others. Treated alloy specimens exhibit improved mechanical properties at ambient temperatures, but a reduction in performance at higher temperatures due to thermal softening. In terms of corrosion resistance, the heat-treated alloy demonstrates superior performance compared to the as-cast alloy, thanks to the presence of protective precipitates and a finer microstructure.
