Abstract ：
The near-alpha Ti60 alloy, renowned for its exceptional high-temperature performance, is highly sought after for aerospace applications. This study optimized the laser powder bed fusion (LPBF) parameters to fabricate Ti60 alloy with a density approaching 99.84 %. The rapid solidification process inherent to LPBF results in an ultrafine martensitic microstructure within the Ti60 alloy, characterized by the presence of intricate alpha ' martensite laths within the (3 columnar grains. The alloy's crystallographic structure is distinguished by a high density of dislocations and twins, which significantly augment its mechanical properties at both ambient and elevated temperatures. At room temperature, the alloy exhibits a tensile strength of 1402 MPa coupled with a elongation of 12.3 %. At 600 degrees C, these values increase to 686 MPa and 25.6 % elongation, respectively. These findings have the potential to significantly advance the application of LPBF-ed Ti60 alloy in the aerospace sector, while also offering a pivotal reference for the additive manufacturing of other high-performance titanium alloys.

Abstract ：
The development of efficient and stable electrocatalysts for the hydrogen evolution reaction (HER) is essential for the realization of effective hydrogen production via seawater electrolysis. Herein, the study has developed a simple method that combines electrospinning with subsequent thermal shock technology to effectively disperse ruthenium nanoparticles onto highly conductive titanium carbide nanofibers (Ru@TiC). The electronic metal-support interactions (EMSI) resulted from charge redistribution at the interface between the Ru nanoparticles and the TiC support can optimize hydrogen desorption kinetics of Ru sites and induce the hydrogen spillover phenomenon, thereby improving hydrogen evolution. As a result, the Ru@TiC catalyst exhibits outstanding HER activity, requiring low overpotentials of only 65 mV in alkaline seawater at the current density of 100 mA cm-2. Meanwhile, Ru@TiC demonstrates excellent stability, maintaining consistent operation at 500 mA cm(-2) for at least 250 hours. Additionally, an anion exchange membrane electrolyzer incorporating Ru@TiC operated continuously for over 500 hours at 200 mA cm-2 in alkaline seawater. This study highlights the significant potential of robust TiC supports in the fabrication of efficient and enduring electrocatalysts that enhance hydrogen production in complex seawater environments.

Abstract ：
As a representative third-generation Al-Li alloy, 2A97 alloy has attracted significant attention for applications in aeronautics and astronautics, but its poor hot workability and complex thermal deformation behavior, which make for difficult optimization, significantly limit its widespread industrial utilization. In this study, the thermal deformation behavior of 2A97 Al-Li alloy was systematically investigated via thermal compression tests conducted over a temperature range of 260-460 degrees C and strain rates ranging from 0.001 s-1 to 1 s-1. The effects of deformation parameters on the alloy's microstructural evolution were examined using electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM). Based on the dynamic materials model, a constitutive equation was established by analyzing the stress-strain data under various thermal deformation conditions. Furthermore, a thermal processing map was compiled to analyze the effects of the temperature and strain rate on the power dissipation efficiency and flow instability factor. The thermal deformation mechanisms were identified through combined analysis of the thermal processing map and microstructural features. Results indicate that the fraction of low-angle grain boundaries increases with a rising lnZ value (Zener-Hollomon parameter) during the thermal compression process. Dynamic recrystallization is the main deformation mechanism of 2A97 Al-Li alloy in the stable region, whereas the alloy exhibits flow localization in the unstable region. According to the thermal processing map, the optimal hot working windows for the 2A97 Al-Li alloy were determined to be (1) 360-460 degrees C at strain rates of 0.05 s-1-1 s-1, and (2) 340-420 degrees C at strain rates of 0.001 s-1-0.005 s-1. These conditions offer favorable combinations of microstructure and deformation stability, providing critical guidance for the thermo-mechanical processing of 2A97 alloy.

Abstract ：
The tensile behavior of (Fe50Mn30Co10Cr10)100-xSix (x=0 (Si0), 2 (Si2)) metastable HEAs prepared by selective laser melting was studied at cryogenic temperatures. The results demonstrate that the addition of Si leads to lattice distortion and a decrease in stacking fault energy, especially at 77 K, which significantly promotes transformationinduced plasticity (TRIP) in Si2 HEAs. The yield strength, tensile strength, and ductility of Si2 HEAs are 505.2 MPa, 1364.1 MPa, and 19%, which are 43%, 53% and 58% higher than those of Si0 alloy, respectively. TRIP is the main deformation mode, in addition to dislocation slip, and plays a key role in strengthening. The reinforced and continuously sustained TRIP maintains a dynamic strain distribution during deformation. Ultrahigh strain hardening greatly enhances the strength and ductility.

Abstract ：
This study investigates the effects of different annealing parameters on the microstructure, texture, and mechanical properties of hot-rolled pure yttrium plates using electron backscatter diffraction for the first time. With the increase of annealing temperature and time, the volume fraction of low-angle grain boundaries of hot-rolled pure yttrium plate decreases. While the intensity of the texture firstly decreases and then increases. During annealing at 600 degrees C, the {0002} pole density shifted from deviating from the normal direction (ND) by similar to 30 degrees to being in line with the ND as the annealing time increased, forming a typical basal texture. This can be attributed to its unique recrystallization mechanism. The strength and hardness of the as-annealed samples were significantly lower than that under the hot-rolled state, while the elongation increased when compared with the hot-rolled sample. The considerable mechanical properties of pure yttrium plate are obtained by hot rolling and following annealing at 600 degrees C for 1 h.

Abstract ：
To meeting the double demands of structural weight reduction and performance improvement of aerospace vehicle, conventional high-temperature titanium alloys or titanium matrix composites (TMCs) are encountering a huge challenge that the room-temperature ductility will be inevitably deteriorated in pursuit of enhancing the elevated high-temperature strength. The present work proposes a feasible strategy for resolving this contradiction by constructing a novel bimodal architecture and introducing the multiscale reinforcements of microsized TiB whiskers and micro/ nanosized Y2O3 particles. The unique bimodal microstructure consists of primary microsized alpha p/beta lath clusters and micro/nano basketweave-like structure composing of alpha p, secondary nanosized alpha s and beta laths. It is noteworthy that the bimodal (TiB+Y2O3)/Ti composite exhibits excellent mechanical properties with the ultimate tensile strength (UTS) of 1318 MPa with the total elongation to failure (EL) of 10.5% at room temperature, and UTS of 934 MPa with EL of 23 % at 600 degrees C, far higher that of the reported 600 degrees C high temperature titanium alloys or TMCs. In-situ investigations indicate the postponed strain localization, the activated extra (c + a) dislocations within alpha p laths, and the heterogeneous deformation induced (HDI) hardening caused by the unique bimodal microstructure, synergistically promoted the ductility of bimodal (TiB+Y2O3)/Ti composite. While the strength enhancement at room temperature and 600 degrees C is attributed to the synergistic strengthening effect of nanosized alpha s, microsized TiB whiskers and micro/nanosized Y2O3 particles and HDI strengthening. These findings provide a new insight for improving mechanical properties of metal matrix composites.

Abstract ：
Through the surface modification of graphene nanoparticles (GNPs) by ethyl cellulose (EC), combined with solution ultrasonic dispersion and wet ball milling, GNPs and aluminum matrix were uniformly mixed and GNPs damage was suppressed. Then, highly wear-resistant GNPs/AlSi10Mg composites were prepared by the suppression of interfacial reaction through rapid sintering with discharge plasma. The microstructure and wear-resistant properties of GNPs/AlSi10Mg composites were characterized and analyzed by scanning electron microscope, transmission electron microscope and friction testing machine. The results show that moderate addition of GNPs can effectively improve the mechanical properties of the composites. When the addition amount of GNPs is 0.5wt%, the wear rate and coefficient of friction of the composites are the lowest, which are 7.8×10-4 mm3/(N·m) and 0.417, respectively. The wear rate is reduced by 28.4% compared with that of the matrix material (10.9×10-4 mm3·N-1·m-1). The wear mechanism of GNPs/AlSi10Mg composites is mainly abrasive wear, accompanied by slight oxidative wear and adhesive wear. During the friction process, when the composite specimen is in contact with the dyad, GNPs emerge on the surface to form a thin film under the action of shear force, which can be used as a lubricant to reduce the contact point between the dyad and the matrix, preventing excessive spalling and delamination and thereby protecting the matrix. © 2025 Science Press.

Abstract ：
The microstructure of commercially pure titanium subjected to uniaxial compression was meticulously analyzed using electron backscattered diffraction (EBSD) to investigate the variant activation behavior of {11-22} twins and {10-12} twins. The results reveal that the type and number of activated twin variants are strongly dependent on the loading direction-whether applied along the normal direction (ND) or the rolling direction (RD). Notably, loading along ND can activate up to five twin variants, and most are activated with low Schmid Factor (SF) rank but high SF value. The variation in the number of activated twin variants within a grain is influenced by factors such as grain size, the activation stress of twinning versus slip, and the orientation of the loading direction relative to the c-axis. SF value for two twinning systems ({11-22} twins and {10-12} twins) were systematically calculated in pure titanium as a function of the angle between the c-axis and the loading direction, which indicates that compression along a direction closely aligned with the c-axis has the potential to activate up to six variants of {11-22} twins simultaneously. In contrast, compression perpendicular to the c-axis tends to activate fewer {10-12} twin variants, with the twinning activation being highly sensitive to the degree of c-axis rotation.

Abstract ：
In order to achieve in-situ growth of layered double hydroxides (LDH) film on plasma electrolytic oxidation (PEO) coating of AZ31B magnesium alloy under mild conditions, a facile method was used in this work, that is ethylenediaminetetraacetic acid (EDTA)-assisted growth method. Compared to the conventional hydrothermal method, the fabrication of LDH/PEO composite coating by this method does not require a high temperature and high pressure environment and is not constrained by the size of the reactor. Furthermore, the obtained LDH/PEO composite coating exhibits enhanced corrosion protection, which will be widely applied in corrosion protection field of surface engineering. In this work, an effective strategy to control the dissolution of PEO coating and the growth of LDH film by regulating the concentration of EDTA was proposed, after revealing the growth behavior of LDH on PEO coating during this facile fabrication process. The growth behavior of LDH film can be briefly summarized in three stages: PEO coating dissolution, LDH nucleation, and LDH growth. Interestingly, the growth mechanism of LDH was changed with EDTA assistance. LDH shifted from preferential growth within the micropores of the PEO coating to uniform growth. With the assistance of 0.06 M EDTA, which is optimal, the dissolution of original PEO coating provided a stable and sufficient Mg source for the growth of LDH film, resulting in a dense LDH network structure on the PEO coating. This uniformly grown LDH film could not only seal the inherent defects of the PEO coating but also exhibited the ability to adsorb corrosive anions, which increases the tortuosity and difficulty in penetration of corrosive media, significantly improving the corrosion resistance of the LDH/PEO composite coating.
