Summary: A commercially pure (CP) Zr coating with high microhardness (387 +/- 26 HV0.025) was successfully deposited onto a CP-Al coated Mg alloy using a high pressure cold spray (HPCS) system. The Zr particles influenced the Al layers beneath the Zr coating, leading to noticeable densification. The Zr/Al coated Mg alloy exhibited the highest charge transfer resistance (Rct), polarization resistance (Rpol), and corrosion resistance (|Z|f=0.01Hz) after 24 hours of immersion in 3.5 wt% NaCl electrolyte. Additionally, the Zr/Al coating showed the lowest wear rate, which can be attributed to its higher hardness due to smaller crystallite size and higher dislocation density.

Summary: The research proposes a hybrid of silk fibroin and sodium alginate to improve the adhesion force and mechanical properties of composite coatings on hydrophilic Mg-Zn-Ca alloy surfaces. Different mass ratios of sodium alginate were tested to achieve the optimum coating strategy, resulting in significantly improved adhesion force and mechanical properties index compared to pure silk fibroin or sodium alginate coatings. The addition of sodium alginate also delayed the corrosion rate of the coated Mg-Zn-Ca alloy, offering more possibilities for the controllable surface performance of degradable metals.

Summary: The micro addition of Ca effectively increases the strength and ductility of Mg-Zn-Ce alloy by enhancing alloying segregation at grain boundary. The addition of Ca leads to enhanced Zn segregation and co-segregation of Zn, Ce, and Ca. This is attributed to the decreased segregation energy and promoted diffusion process of Zn by Ca, which accelerates the thermodynamic and kinetic process of segregation. The controllable segregation at grain boundary, induced by Ca, contributes to the development of advanced magnesium alloys by stabilizing grain boundary, refining grain size, inhibiting dislocation mobility, improving strength, and enhancing grain boundary cohesion and ductility.

Summary: Organic materials with controllable molecular design, such as crystalline quinones, show promise as electrode materials in rechargeable batteries due to their voltage tunability and environmental friendliness. However, the detailed mechanism of proton-coupled electron transfer (PCET) in quinone crystals remains elusive. In this study, the performance of the density functional tight-binding (DFTB) method, specifically DFTB3, in describing charge transport in crystalline quinones was benchmarked. The results highlight the deficiencies of DFTB3 in accurately predicting the proton affinity, structural, and electronic properties of crystalline quinones, calling for further development of the DFTB method in this context.

Summary: The microstructure evolution and mechanical properties of the as-drawn dilute Mg-0.8Al-0.1Ca-0.6Mn alloy wires during annealing and peak-aging treatment were investigated. The study revealed that the high density of nano-sized Al-Mn precipitates hindered grain boundary migration and restricted grain growth during low-temperature annealing, while partial dissolution of Al-Mn precipitates led to obvious grain growth and increased uniformity of recrystallization grain size during high-temperature annealing. Additionally, there was a growth preference in grains with a specific orientation, which was closely associated with texture changes. Furthermore, the alloy exhibited a significant age-hardening response after peak-aging treatment at 500 degrees C for 10 minutes, resulting in simultaneous improvement of tensile yield strength and elongation to failure, which was mainly attributed to the formation of monolayered Guinier-Preston (G.P.) zones and planar Al2Ca precipitates.

Summary: This study reports the influence of grain boundary segregation on microstructure development during hot-rolling of AZ31 alloy. Annealing at 420 degrees C induces strong grain boundary segregation, promoting dynamic recrystallization and strong basal texture. Annealing at 500 degrees C reduces grain boundary segregation, hindering dynamic recrystallization and resulting in a weak rolling-direction-split texture, improving the stretch formability of the alloy sheet.

Summary: A high-performance Mg-8Gd-4Y-0.5Mn-0.2Sc alloy was fabricated using homogenization, hot extrusion, and ageing. The microstructure evolution during homogenization was studied, and an optimum time of 18 h was determined to minimize the volume fraction of second phase particles and maintain a fine grain structure. The alloy exhibited excellent age-hardening ability and strength after peak-aged treatment, with a tensile yield stress of 441 MPa and an ultimate tensile strength of 506 MPa. The high yield strength was attributed to the co-existing bimodal microstructure, fine dynamically recrystallized grains, dense precipitated particles, and nano-scale precipitates. Precipitation strengthening was revealed as the dominant strengthening mechanism.

Summary: This paper reports the application of cold-sample rolling (CSR) processing in a Mg-6Al-1Zn alloy sheet, which resulted in a high fraction of double twins and a substantial texture-weakening effect. Compared to high-temperature rolling (HTR) processing, CSR processing induced a relatively higher texture-weakening effect. The results indicate that twinning-mediated static recrystallization is essential for texture weakening in Al-concentrated Mg-alloy sheets.

Summary: The effect of micro-texture on the tensile properties and room-temperature stretch formability of Mg-Al-Zn alloy sheet was studied. The introduction of micro-texture through solution treatment, hot-rolling, and post-annealing increased the fraction of a unique texture component, which improved the limiting dome height without compromising the strength due to the high activity of tensile twinning and minimal change in the Schmid factor for basal slips. This finding highlights the importance of micro-texture designing for the development of high strength-formability synergy in magnesium alloy sheets.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
