Summary: This study systematically investigates the microstructure evolution and mechanical properties of Steel/Mg composites. It is found that there is an interdiffusion phenomenon of Mg and Zn elements at the interface of the composites, forming an interdiffusion layer and compounds. The inclusion of steel wire can effectively reduce the texture strength of the Mg alloy matrix, and the Steel/Mg composites exhibit higher tensile and compressive strength compared to Mg-R. This research provides a novel, time-saving, and cost-effective method for manufacturing continuous fiber reinforced metal matrix composites (CFRMMCs), expanding the application of metal composites.

Summary: The study successfully fabricated SiCN honeycomb ceramic with excellent mechanical and microwave-absorbing properties by optimizing the ratio of multifunctional acrylates. At low temperatures, the free carbon nanodiamonds formed through the copolymerization of acrylate and polysilazane give SiCN honeycomb ceramic an extremely high microwave absorption rate.

Summary: This study developed a multi-material extrusion-based additive technique to fabricate porous Mg/bioceramic composite scaffolds for the treatment of femoral nonunion with large segmental bone defect. The technique allowed for the fine-tuning of printable inks to optimize the dispersion of micro-sized particles. The fabricated composite scaffolds exhibited high relative densities and proper interfacial bonding between the bioceramic particles and the Mg alloy matrix. They possessed desired biodegradability, bone-mimicking mechanical properties throughout the in vitro biodegradation period, and improved bioactivity to bone cells. These results demonstrate the great potential of extrusion-based 3D printed porous Mg materials as ideal biodegradable bone-substituting materials.

Summary: This paper investigates the superior energy-absorbing characteristics of hollow-cylindrical-joint hierarchical honeycomb composite tubes under axial quasi-static crushing. The experimental results show that the fiber orientation has a significant effect on the energy-absorbing characteristics of these structures, and the energy-absorbing capacity of the composite structures can be enhanced by integrated biomimetic design.

Summary: This research investigates the effects of the layer thickness ratio (LTR) on the bendability of laminated composite sheets of dissimilar magnesium alloys. It is found that the optimum bendability is achieved at an LTR of 2:1 when the outer layer is made of magnesium alloy Gd. This phenomenon can be explained by the improved plasticity of the outer layer and the enhanced tensive-compressive asymmetry of the inner and outer layers.

Summary: In this study, ultrafine-grained Mg-3Zn-1.2Ca-0.6Zr alloy was prepared using a novel extrusion-shear process. The compressive deformation process was found to follow three stages with twinning and dislocation slip playing a significant role in the evolution of the alloy's microstructure. Increase in strain rate promoted interaction between twin and dislocation slip, leading to enhanced deformation, while the dominance of dislocation mechanism was observed in the later stage with increasing dislocation density.

Summary: The study investigated the influence of Mn content (0.4, 0.8, 1.2 wt.%) on the microstructure and mechanical properties of as-extruded dilute binary Mg-Mn alloys. Increasing Mn content resulted in a decrease in the volume fraction and size of dynamically recrystallized (DRXed) grains. Segregation of Mn atoms and nano alpha-Mn dynamical precipitates were observed at the grain boundaries, with the amount of precipitates increasing with Mn content. Tensile tests showed that Mn content significantly affected mechanical properties, with the Mg-0.8 wt.% Mn alloy exhibiting excellent ductility at room temperature.

Summary: This study investigated the TRIP effect in Mg-Sc alloys with a beta single-phase structure. The results showed that the presence of a hexagonal close-packed phase led to a strain-induced martensitic transformation, resulting in superior ductility. The Mg-Sc alloys exhibited high fracture strain and ultimate tensile strength, overcoming the limitations of conventional Mg alloys.
