Summary: A combination of experimental and numerical studies was conducted to understand the microstructure and formation mechanism of kink bands in alpha/beta two-phase titanium alloys. Deformation kink bands were introduced in a Ti-9Cr alloy, and the strength changes of the alpha and beta phases inside and outside the kink band were evaluated. Microstructural examination and crystallographic analysis revealed the presence of prismatic slip during compression, and a crystal plasticity finite element model was developed to reproduce the {110}beta-rotation-type kink bands.

Summary: The plastic deformation behavior and microstructural evolution of Ti555211 titanium alloy in different phase zones have been studied. Different deformation activation energies are observed in the dual-phase and single-phase zones, with the former having a higher energy for deformation. Moreover, the size of beta phase grains increases with decreasing strain rate in the dual-phase zone, while it increases significantly with increasing deformation temperature in the single-phase zone. Elongated grains are observed in the microstructures of the alloy subjected to plastic deformation in the single-phase region at higher strain rates. Additionally, it is more difficult for the alloy to induce plastic deformation in the dual-phase region than in the single-phase region.

Summary: Longitudinal-torsional ultrasonic vibration-assisted milling is an effective method for improving the quality of machined surfaces. This study investigated the effects of ultrasonic amplitude, feed rate, and cutting speed on surface morphology, roughness, residual stress, and subsurface microstructure in the end milling of TC18 titanium alloy. The results showed that the milling process with longitudinal-torsional ultrasonic vibration assistance resulted in more distinct surface microtextures at larger amplitude, smaller feed rate, and higher cutting speed. Compared to conventional milling, the ultrasonic vibration-assisted milling generated higher roughness, surface residual stress, and deeper plastic deformation layer in the subsurface. The research provides insights into surface machining of titanium alloy and quality control of machined surface.

Summary: This paper investigated the deformation and fracture behaviors of Co20Cr20Fe20Ni20Mn15Cu5 high entropy alloy plates in shear punching tests. It was found that with the increase of relative clearance, the percentages of deformation zone height and burr zone height also increased, attributed to changes in stress states during the shearing process. A larger relative clearance facilitated more plastic deformation, resulting in numerous slip bands and elongated dimples on the fractured surface.

Summary: In this study, sulfur is incorporated into the polymer chain by chemical polymerization to obtain C3N3S3. Unlike g-C3N4, C3N3S3 does not exist in the form of a graphitic structure and cannot be exfoliated into thin lamellas. However, both polymers have similar optical properties and positions of the conduction and valence bands. Comparative studies show that C3N3S3 exhibits smaller overpotentials for electrochemical oxygen reduction and hydrogen evolution compared to g-C3N4. Additionally, spectroscopic experiments demonstrate that both polymers have high activity in the photocatalytic reduction of oxygen to superoxide anion radical by the photogenerated electrons.

Summary: The production and usage of lithium-ion batteries (LIBs) result in a significant increase in harmful waste, which raises concerns for environmental protection and metal resource scarcity. This paper proposes a novel application of a magnetorheological fluid (MRF) made from LIBs-based liquid waste containing heavy metal ions. The waste is treated with acid-leaching to obtain cobalt-doped superparamagnetic iron oxide nanoparticles (SPIONs), effectively purifying the waste from cobalt. The nanoparticles are then used to prepare the MRF, which demonstrates enhanced viscosity in the presence of magnetic fields. This work presents a cost-effective method for utilizing harmful waste from LIBs and provides a sustainable solution for waste management.

Summary: This study demonstrates the feasibility of introducing nitrogen into titanium dioxide nanotubes by plasma nitriding under ultra-high-vacuum conditions. The resulting nanotubes have a diameter of approximately 110 nm. The study also reveals that alternating nitriding and annealing processes at 450 degrees C lead to the formation of various chemical bonds in the TiO2 crystal structure. The photoactivity of the nitrogen-doped and annealed photoanodes is significantly higher than that of the non-doped ones. The highest maximum photocurrent density is achieved by the double-nitrided and once-annealed sample, which incorporates nitrogen mainly in the interstitial positions in the TiO2 lattice. The thermo-chemical treatment also extends the operational range of the photoanodes towards visible light. Rating: 9/10.

Summary: In this study, the corrosion behavior of two alloys, Ti-29Nb-13Ta-4.6Zr and Ti-45Nb, with similar amounts of β-phase stabilizers, was compared. The corrosion resistance was analyzed in a PBS+H2O2 solution, simulating post-operative inflammation conditions. The results showed that the Ti-29Nb-13Ta-4.6Zr alloy had significantly higher corrosion resistance compared to Ti-45Nb, as evidenced by electrochemical impedance spectroscopy and ion-release measurements. Microscopic analysis also revealed that a thinner layer of oxidation products was formed on the Ti-29Nb-13Ta-4.6Zr alloy surface. These findings suggest that Nb does not play a beneficial role in tailoring the corrosion resistance of Ti-29Nb-13Ta-4.6Zr under simulated inflammatory conditions.

Summary: The study aimed to compare the influence of microstructural and textural changes on the hardening by annealing effect in cold-rolled titanium. Different thickness reductions were applied to produce ultrafine-grained (UFG) Ti Grade 2, and the hardening effect was observed through a short-time annealing process. The results showed that the hardening effect was not related to texture changes, but rather to the annihilation of mobile dislocations and the ordering of the dislocation substructure within coarse grains.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
