Summary: The study shows that Ti-Mo-Fe alloys offer significant cost savings on raw materials compared to current commercial biomedical Ti alloys, with excellent mechanical properties achieved through compositional adjustments. Porous Ti-10Mo-5Fe alloys with increased porosity through space holder additions exhibited decreased compressive strength and elastic modulus but are promising for hard tissue engineering applications due to their optimal pore sizes.

Summary: In this study, Ti-2Mn, Ti-2Mn-2Sn, Ti-4Mn, and Ti-4Mn-2Sn alloys were manufactured by powder metallurgy, and the impact of slight Sn on the properties of Ti-Mn alloys was investigated. The addition of Sn effectively decreased the alloy's melting point, ideal sintering temperature, and sintering time. Sn favored compressibility, encouraged densification, and refined the size of α and β phases in Ti-2Mn alloy, resulting in enhanced ductility, excellent strength, and improved corrosion resistance. However, the addition of Sn hindered densification and promoted β phase coarsening in Ti-4Mn alloy, leading to little improvement in ductility and deterioration of corrosion resistance.

Summary: The study focused on the processing of titanium-based implants with improved corrosion resistance and Young's modulus close to that of cortical bone. Titanium matrix, hydroxyapatite, and hydroxyapatite-zirconia reinforced composites were successfully produced and tested for microstructure, mechanical, and corrosion properties. The Ti/(HA+ZrO2) composite scaffold showed higher corrosion resistance than the scaffold reinforced with only the HA phase, making it suitable for orthopedic and dental applications.

Summary: Titanium (Ti) is widely used in biomedical implants due to its excellent mechanical properties and biocompatibility. However, the stress shielding effect limits its application. Incorporating bioactive elements into titanium alloys, such as magnesium (Mg), can provide specific biological functions through sustained release. Despite the incompatibility between Ti and Mg, Ti-Mg composites have potential for biomedical applications, and their preparation methods, properties, and biocompatibility are discussed in this review.

Summary: The CoCrFeNiAl0.3 high entropy alloy samples were produced using different ball milling strategies, and the microstructure and phase formation were investigated. The study found that mechanical mixing resulted in a mixture of FCC and BCC structured matrix, as well as intermediate multiphases, while mechanical alloying produced a single phase FCC matrix. The microstructure exhibited good thermal stability, attributed to the pinning effects of dispersed Al2O3 nanoparticles. The Al2O3 nanoparticles played a dominant role in improving the mechanical properties.

Summary: This study investigates the influence of oxygen impurities at different locations, such as lattice oxygen and grain edge oxygen, on the thermal resistivity of AlN ceramics. The results show that lattice oxygen is the main factor, and high-temperature annealing and pre-sintering can reduce the lattice oxygen content. The volume fraction of grain edge phase has little effect on thermal resistivity.

Summary: This study provides a homogenization method to investigate the impact of interfacial characteristics on the thermal conductivity of GF/Cu composites. Finite element homogenization method is used to establish representative volume element models of material microstructure and interfacial layers, taking into account the distribution morphology and thermophysical properties of interface compositions. The results indicate that the thermal conductivity of GF/Cu composites is significantly influenced by factors such as graphite sizes, graphite volume contents, interface contents, pore shapes, the relative density of interfacial layers, and whether the interface component is continuous.

This study uncovers a Mn activation mechanism in a novel P2-Na0.80Li0.08Ni0.22Mn0.67O2 cathode, which achieves high discharge capacity and long cycling life by triggering anionic redox and reducing Mn through oxygen loss. The work elucidates the charge compensation mechanism and expands the horizons of oxygen redox chemistry for high-performance layered oxide cathode materials in sodium-ion batteries.

Summary: Ductility deterioration induced by L21-Ni2AlTi precipitates in aged ferritic alloys was systematically examined using scanning transmission electron microscopy, mechanical tests, and first-principles thermodynamic calculations. Experimental studies showed that the presence of B2-NiAl and L21-Ni2AlTi precipitates in the alloy resulted in higher strength and hardness compared to the alloy with only NiAl precipitates, but a significant decrease in elongation-to-failure, indicating obvious ductility deterioration. Theoretical analysis revealed the intrinsic brittleness of L21-Ni2AlTi phase and L21-Ni2AlTi/BCC-Fe interface.

Summary: This paper examines the wetting behavior of copper droplet on a graphite substrate using molecular dynamics simulation. It finds that the wetting process is influenced by Ar pressure, with hindered wetting at low temperatures and promoted wetting at high temperatures. However, beyond a certain Ar pressure, further increase does not improve wetting, and Ar pressure increases the potential of mean force between the copper droplet and the graphite substrate, making detachment more difficult.

Summary: In this paper, the regulation of crystal structure and orientation during direct current (DC) electrodeposition for achieving performance control of electrodeposited copper films was investigated. It was found that electrolyte aging during continuous DC electrodeposition in acidic electrolytes containing additives promoted spontaneous transformation of copper crystal structure. A special crystal structure composed of vertical twins with high aspect ratio and (220) orientation was revealed, which was mainly attributed to energy minimization in the deposited film. The generation priority of vertical twins was found to be between the equiaxed structure (UD-type) and the (1 1 1) textured columnar structure (FT-type). Complex interactions and degradation of additives were identified as the driving forces for crystal transformation. Additionally, the surface roughness changed with the transformation process of the crystal structure, providing a potential method for regulating the surface roughness of copper films.

Summary: Hollow spherical WO3 powder was successfully synthesized via spray solution combustion synthesis (SSCS) method using a mixed solution of ammonium metatungstate, glycine and ammonium nitrate. The effects of fuel ratio, temperature, and precursor solution concentration on the structure and morphology of the powder were investigated, as well as the SSCS mechanism. The optimized conditions resulted in the formation of smooth-surfaced spherical WO3 powder with a median diameter of 24.02 μm, consisting of nanoparticles with a diameter of about 30 nm and a specific surface area of 13.5 m2/g. The as-synthesized WO3 powder exhibited excellent catalytic performance in degrading RhB solution under visible light, with 70.1% degradation achieved within 2 hours using only 10 mg of powder.

Summary: Selective laser melting (SLM) of tungsten (W) is challenging due to its high melting point and brittleness. In this study, high-density crack-free SLM W was successfully fabricated by modifying powders and optimizing process parameters. The laser energy density and hatch distance were found to be crucial in controlling the quality of SLM W. The microstructure changed upon annealing at 1200 degrees C, resulting in reduced anisotropy of mechanical properties.

Summary: In this study, PH13-8Mo stainless steel parts doped with cerium were fabricated and compared with undoped parts. The doping of cerium improved the microstructure, phase constituents, and tensile properties of the stainless steel. The results showed that doping with cerium enhanced the mechanical stability of austenite, improved the sphericity of oxide inclusion, and increased the ultimate tensile strength and fracture elongation of the PH13-8Mo parts. The improved strength and ductility were attributed to the strengthening effects of nanoscale precipitation and grain refining, as well as the enhanced inclusion sphericity and coherency between the inclusion and matrix.
