Summary: Magnesium (Mg)-based alloys and composites are attracting attention due to their ability to degrade in the body. Graphene nanoplatelets (GNPs) are considered a promising reinforcement for Mg matrix nanocomposites (MMNCs) to enhance mechanical strength and corrosion resistance. This study investigated the effects of adding 0.1-0.3 wt% GNPs on MMNCs, showing improvements in compressive strength and corrosion resistance, with higher GNP content leading to decreased Mg2+ ion release during degradation.

Summary: There is great interest in using severe plastic deformation (SPD) to improve the performance of magnesium for biological applications. However, contradictory reports exist regarding the properties and trends. This study reviews the structural features, mechanical properties, corrosion behavior, and biological response of magnesium and its alloys processed by SPD, with a focus on equal-channel angular pressing (ECAP) and high-pressure torsion (HPT). The results show that grain refinement through SPD can improve the mechanical properties and corrosion resistance of magnesium without compromising the biological response, indicating the great potential of SPD for enhancing the performance of magnesium for biological applications.

Summary: In this study, the texture evolution of two Mg materials during tension is investigated. It is found that pure Mg and Mg-15Gd alloy exhibit different deformation modes, with pure Mg showing a dominant prismatic slip and Mg-15Gd alloy showing a complex behavior of twinning and multiple slips. The critical resolved shear stress ratios between non-basal slip and basal slip are lower for Mg-15Gd alloy compared to pure Mg.

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: 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.

Summary: The increasing prevalence of bone-related injuries and aging geriatric populations are driving the growth of the orthopaedic implant market. A hierarchical analysis of bone remodelling after material implantation is necessary to understand the relationship between implant and bone. Osteocytes play a vital role in bone health and remodelling processes, making it essential to examine the lacuno-canalicular network (LCN) in response to implant materials. Biodegradable materials, such as magnesium alloys, offer a potential solution to permanent implants, and surface treatments like plasma electrolytic oxidation (PEO) can slow degradation. This study investigates the impact of PEO-coated WE43 on the LCN using nondestructive 3D imaging, and the findings suggest that slower degradation induced by PEO-coating results in healthier lacunar shapes within the LCN.
