Summary: In this study, graphene reinforced magnesium matrix composites were prepared using the in situ liquid-state method. The tensile strength of the composites was improved by increasing the content of graphene nanoparticles (GNPs). Additionally, the composites exhibited a significant plastic deformation stage, with the ductility of the 0.12 GNPs/Mg6Zn composites reaching 27.6%. Thus, this novel preparation method has great potential for fabricating Mg matrix composites with high strength and high ductility.

Summary: Multi-pass caliber rolling was used on in-situ AlN/AZ91 composite rods, resulting in high yield strength, ultimate tensile strength, fracture elongation, and good surface morphology. The study found that caliber rolling refined the grains of the composite rods and induced twinning-induced dynamic recrystallization. The reinforcement of in-situ AlN promoted the formation of twinning-induced DRX. The increased yield strength was mainly attributed to solid solution atoms, twinning-induced DRX, discontinuous DRX, high density dislocations, and nano-sized precipitates. High ductility was mainly due to grain size refinement, weakened texture, and activation of non-basal slip systems at room temperature.

Summary: The Y2O3p/ZG21 composites underwent significant changes in microstructure and mechanical properties after rolling and annealing processes. Deformed microstructure with twins and shear bands, as well as a basal texture with double peaks, were observed after rolling; while a recrystallized microstructure and circle multi-peaks texture were obtained after annealing. The anisotropic yield strength and superior ductility of the composites were attributed to the asynchronous change of texture components during annealing and different deformation mechanisms.

Summary: This study investigated the effect of extrusion parameters on the microstructural evolution and tensile properties of a Mg-8.0Gd-4.0Y-1.0Mn-0.4Sc alloy. Different DRX mechanisms, such as DDRX and CDRX, were identified, and the alloy with larger extrusion ratio exhibited smaller DRXed grains and a high number of fine precipitated particles. The alloy extruded at 400°C and ratio of 20:1 showed superior strength, while alloy extruded at 450°C and ratio of 10:1 exhibited higher elongation to failure. The enhanced strength was attributed to strong basal texture, refined DRXed grains, and dense distribution of fine particles.

Summary: This study developed novel Al clad Mg composites through continuous extrusion method, showing good metallurgical bonding between the Al shell and Mg core even without preheating of the Mg alloy. The fine-grained microstructure contributed to a significant enhancement in ultimate flexural strength (UFS) to 452 MPa. Preheating of the Mg alloy resulted in complete dynamic recrystallization (DRX) and modified texture of the Mg alloy, leading to a significant improvement in the bendability of the Al/Mg composite.

Summary: The synergistic effects of partial replacement of Al with Ca, homogenization heat treatment, and hot extrusion on the microstructure and mechanical properties of Mg-(7-x)Al-xCa magnesium alloys were studied. Homogenization resulted in eutectic constituents spheroidization and tensile ductility improvement, while hot extrusion led to fragmentation and dispersion of particles, formation of fine microstructures, and profound enhancements of tensile properties. The extruded AX43 alloy showed significantly better product of strength and ductility compared to the as-cast counterpart.

Summary: This work focuses on improving the strength, ductility, and elastic modulus of magnesium matrix composites (MMCs) by reinforcing Mg-3Al-1Zn composites with micron-sized Ti particles through powder metallurgy. The addition of Ti particles increases the yield strength, elongation, and elastic modulus. The formation of TiAl phase and MgO layer at the interface enhances the interfacial bonding between Ti particles and the Mg matrix. The composite with 9Ti/Mg-3Al-1Zn composition exhibits the best mechanical properties with high strength and improved ductility due to grain refinement and collaborative deformation of Ti particles.

Summary: In order to improve the room temperature comprehensive mechanical properties of the refractory high entropy alloy Hf0.5Mo0.5NbTiZr, boron element was added to form the boride phase as the strengthening phase. The addition of boron led to the formation of boride phase, affecting the microstructure and mechanical properties of the alloy. The study showed improvements in strength and ductility with low levels of boron, but a decrease in ductility with higher boron content due to the formation of brittle boride phase.

Different extrusion temperatures were tested to investigate their effect on the microstructure and properties of TID-processed Mg-4Zn-1Ca alloys. The results showed that the combination of TID and extrusion temperature significantly influenced grain refinement, with the best microhardness and compressive yield strength values observed at 300 degrees C.

Summary: A new method of synthesising porous Mg materials has been successfully explored by incorporating the turning-induced deformation (TID) method with sintering. The synthesized Mg materials exhibited comparable properties to previously-synthesised porous Mg materials, with subsequent sintering resulting in a more consistent mechanical response, especially with microwave sintering. The materials showed mechanical response within the range of human cancellous bone and, when reinforced with biocompatible silica nanoparticles, presented an optimal combination of mechanical properties for potential use as biodegradable implants due to their similarity to cancellous bone.

Summary: Magnesium implants that are biocompatible and biodegradable are crucial for orthopaedic applications. However, the biocompatibility, degradability, corrosion behavior, and bioactivity of Mg-based alloys can vary depending on composition and microstructure. This study examined the cytotoxicity, hemocompatibility, corrosion, and biomineralization of pure Mg and its nanocomposites to assess their suitability as biodegradable materials. The results showed that pure Mg and its nanocomposites responded differently in different tests, suggesting that comparing Mg nanocomposites could be a more effective strategy for orthopaedic implant applications.

Summary: Abundant {10-12} twins were observed in a extruded Mg-2.8Y (wt. %) sheet with RE texture during compression and reverse tension. The deformation mechanisms were studied quantitatively, and twin variants with higher Schmid factors were activated preferentially. The crystallographic characteristics of twinning transfer were analyzed through grain boundary misorientation angle and geometric compatibility factor. The distribution of short twin chains and restriction of long twin bands were influenced by texture and loading path.
