This study designs and synthesizes highly dense Li2Mg6ZnTi6O20 microwave dielectric ceramics based on a high-entropy strategy, focusing on achieving stable structures, low sintering temperatures, and excellent comprehensive performance. The ceramics exhibit a predominant face-centered cubic disordered phase (Fd-3m) sintered at 1200–1280°C, alongside an increased presence of the second phase MgTiO3 at higher temperatures. Remarkably, these ceramics demonstrate excellent microwave dielectric properties (εr = 16.69, Q × f = 88,230 GHz, and τf = −36.5 ppm/°C). Additionally, we have explored the addition of x wt% LiF (1 ≤ x ≤ 5) to the Li2Mg6ZnTi6O20 ceramics to enhance their applicability. The ceramics feature a spinel structure for LiF contents up to 3 wt%, while higher LiF concentrations induce the formation of a secondary phase, LiTiO2, characterized by a rock salt structure. Notably, the lattice distortion induced by LiF leads to a constant decrease in εr. A moderate degree of lattice distortion serves to enhance the lattice stability of ceramics, which is reflected in increased lattice energy. Excellent microwave dielectric properties (εr = 16.23, Q × f = 89,728 GHz, τf = −43.5 ppm/°C) were obtained for x = 3 ceramic sintered at 1140°C. Even at x = 5, the ceramic retains excellent microwave dielectric properties (εr = 16.02, Q × f = 63,079 GHz, τf = −26 ppm/°C) at a low sintering temperature of 900°C. This work realizes the multiple effects of LiF and confirms good chemical compatibility with silver for LTCC (low-temperature co-fired ceramics) applications.
本研究基于高熵策略设计并合成了高致密 Li2Mg6ZnTi6O20 微波介电陶瓷，重点是实现稳定的结构、较低的烧结温度和优异的综合性能。这些陶瓷在 1200-1280°C 烧结温度下呈现出主要的面心立方无序相（Fd-3m），同时在较高温度下第二相 MgTiO3 的存在也有所增加。值得注意的是，这些陶瓷具有优异的微波介电性能（εr = 16.69、Q × f = 88,230 GHz 和 τf = -36.5 ppm/°C）。此外，我们还探索了在 Li2Mg6ZnTi6O20 陶瓷中添加 x wt% LiF（1 ≤ x ≤ 5）的方法，以提高其适用性。当锂辉石含量不超过 3 wt% 时，陶瓷具有尖晶石结构，而当锂辉石含量更高时，则会形成以岩盐结构为特征的次生相 LiTiO2。值得注意的是，LiF 诱导的晶格畸变会导致 εr 不断减小。适度的晶格畸变可增强陶瓷的晶格稳定性，这反映在晶格能的增加上。在 1140°C 下烧结的 x = 3 陶瓷具有优异的微波介电性能（εr = 16.23，Q × f = 89,728 GHz，τf = -43.5 ppm/°C）。即使在 x = 5 时，陶瓷也能在 900°C 的低烧结温度下保持优异的微波介电性能（εr = 16.02，Q × f = 63,079 GHz，τf = -26 ppm/°C）。这项工作实现了 LiF 的多重效应，并证实了它与银在 LTCC（低温共烧陶瓷）应用中良好的化学兼容性。

Maintaining high piezoelectric response and piezoelectric temperature stability of lead-based piezoceramics is critical for applications under high-temperature environments. Unfortunately, the piezoelectric response of lead-based piezoceramics shows strong temperature dependence. Herein, an innovative strategy was proposed to solve this problem. The method consisted of constructing “slush-like” polar states by introducing localized heterostructures in the tetragonal phase structure to lower the energy barriers. The presence of the tetragonal phase stabilized the domain structure, providing excellent temperature stability, while the localized heterostructures also flattened the free energy landscape and enhanced the piezoelectric response. The strategy was implemented by using 0.11Pb(In0.5Nb0.5)O3-0.89Pb(Hf0.47Ti0.53)O3(PIN-PHT) piezoceramics doped with heterovalent ion Nb5+ to form a “slush-like” polar state with strong interactions inside the ceramics. The piezoelectric response and relaxor behavior of the ceramics were then investigated using piezoelectric force microscopy to reveal the mapping relationship between the complex ferroelectric domain structure and both the piezoelectric response and temperature stability. At Nb5+ doping amount of 0.8 mol%, the ceramics showed excellent comprehensive performances with d33 = 764 pC/N, Tc = 319.1 °C, = 3253.59, kp = 0.67, and tanδ = 0.0122. At an external ambient temperature of 300°C, the d33 of PIN-PHT-0.8Nb5+ remained high at 734 pC/N, with piezoelectric performance retention of 96.1%, showing excellent temperature stability. Overall, a new path was proposed for developing Pb-based piezoceramics with both good piezoelectric response and high-temperature stability, promising to broaden the temperature range of high-temperature piezoceramics for various applications.

Carbon materials have made significant progress in the field of microwave absorption (MA), but achieving wide effective absorption bandwidth (EAB) at low filler content still remains a great challenge. In this work, we design multi-shell bowl-like mesoporous carbon microspheres (MBMCs) by a facile hard template method for efficient MA. It is demonstrated that the spacing between inner and outer shell and second shell thickness play a vital role on the configuration of carbon microspheres. By controlling the second addition of silica template, the microstructure of carbon microsphere evolves from spherical to bowl shape geometry. Expanded shell spacing is beneficial for forming bowl-like microsphere. The dielectric loss and MA properties are highly associated with the configuration of MBMCs. Well-proportioned MBMCs with appropriate shell spacing present wide EAB of 7.3 GHz under a low filling ratio of 12 wt.%. This work paves a new way to broaden EAB and lower filling content of carbon materials via asymmetric multilayer microstructure design.

Developing high-performance alloys with gigapascal strength and excellent ductility is crucial for modern engineering applications. The concept of multi-component high/medium entropy alloys (H/MEAs) provides an innovative approach to designing such alloys. In this work, we developed the Co1.5CrNi1.5Al0.2Ti0.2 MEA, which exhibits outstanding mechanical properties at room temperature through low-temperature pre-aging followed by annealing treatment. Tensile testing reveals that the MEA possesses an ultrahigh yield strength of 200785 MPa, an ultimate tensile strength of 2365 70 MPa, and exceptional ductility of 15.8% 1.7%. The superior tensile properties are attributed to the formation of fully recrystallized heterogeneous structures (HGS) composed of ultrafine grain (UFG) and fine grain (FG) regions, along with discontinuous precipitation of coherent nano-size lamellar L12 precipitates. The mechanical incompatibility between the UFG region and the FG regions during deformation induces the accumulation of a large number of geometrically necessary dislocations at the interface, resulting in strain distribution and hetero-deformation-induced (HDI) stress accumulation, contributing significantly to HDI strengthening. HDI strengthening, precipitation strengthening, and grain boundary strengthening are the primary mechanisms responsible for the ultra-high yield strength of the MEA. During deformation, the dominant deformation mechanisms include dislocation slip, deformation-induced stacking faults, and Lomer–Cottrell locks, with minor deformation twinning. The synergistic interaction of these multiple deformation modes provides the MEA with excellent work hardening capability, delaying plastic instability and achieving an excellent combination of strength and ductility. This study provides an effective strategy for synergistically strengthening MEAs by combining HDI strengthening with traditional strengthening mechanisms. These findings pave the way for the development of advanced structural materials with high performance tailored for demanding applications in engineering.
开发具有千兆帕强度和优异延展性的高性能合金对现代工程应用至关重要。多组分高/中熵合金（H/MEAs）的概念为设计此类合金提供了一种创新方法。在这项研究中，我们开发了 Co1.5CrNi1.5Al0.2Ti0.2 MEA，通过低温预时效和退火处理，该合金在室温下表现出卓越的机械性能。拉伸测试表明，MEA 具有 20±±0785 兆帕的超高屈服强度、2365 ±±70 兆帕的极限拉伸强度和 15.8% ±±1.7% 的优异延展性。优异的拉伸性能归功于由超细晶粒（UFG）和细晶粒（FG）区域组成的完全再结晶异质结构（HGS）的形成，以及连贯的纳米级片状 L12 沉淀的不连续析出。在变形过程中，超细晶粒区和细晶粒区之间的机械不相容性会在界面上诱发大量几何必要位错的积累，导致应变分布和异变形诱导应力（HDI）积累，从而极大地促进了 HDI 的强化。HDI 强化、沉淀强化和晶界强化是 MEA 产生超高屈服强度的主要机制。在变形过程中，主要的变形机制包括位错滑移、变形引起的堆积断层和 Lomer-Cottrell 锁，以及轻微的变形孪生。这些多种变形模式的协同作用使 MEA 具有出色的加工硬化能力，延缓了塑性不稳定性，实现了强度和延展性的完美结合。这项研究通过将高密度互联强化与传统强化机制相结合，提供了一种协同强化 MEA 的有效策略。这些发现为开发高性能的先进结构材料铺平了道路，使其能够满足工程领域的苛刻应用要求。

The role of cerium (Ce) in enhancing the hot ductility of super austenitic stainless steel S32654 at 850–1250°C was systematically unveiled through theoretical calculations and microstructure characterization. The results indicated that Ce microalloying improved the hot ductility of S32654 throughout the entire deformation temperature range. Specifically, the addition of Ce greatly enhanced the hot ductility in the low (850–900°C) and high (1100–1250°C) temperature ranges, but only slightly increased that in the medium temperature range (900–1100°C). At 850–900°C, Ce addition not only reduced the sulfur (S) content and suppressed the S segregation at the grain boundary, but also promoted the formation of slip bands and deformation twins, apparently improving the hot ductility. At 900–1100°C, Ce addition promoted the nucleation of intergranular σ phases and dynamic recrystallization (DRX) grains, which have adverse and beneficial effects on the hot ductility, respectively. As the temperature increased, the precipitation tendency presented a first increasing and then decreasing trend around 1000°C, while the DRX gradually increased. Accordingly, the improvement degree of Ce on the hot ductility first weakened and then enhanced. At 1100–1250°C, Ce significantly promoted the DRX to form more fine and uniform deformation structure, thereby remarkably increasing the cracking resistance and then the hot ductility.

The evolution of fretting wear behavior of zirconium alloy cladding tubes mated with dimples under the gross slip regime (GSR) was investigated. The findings revealed that the primary wear mechanisms under GSR were delamination, surface fatigue wear and abrasive wear, and the fretting damage rate mainly depends on delamination. The cross-sectional microstructure of the worn area could be divided into the third-body layer, tribologically transformed structure layer, and general deformation layer, with their formation mechanisms analyzed. Furthermore, the mechanism of wear-induced grain refinement was identified as dynamic recrystallization (DRX), including both continuous DRX and discontinuous DRX. Additionally, the processes of fretting wear and DRX were discussed.

Silicon-based (Si-based) materials with high specific capacity are driving the electric vehicle industry and the power storage market. However, poor electrical conductivity and volume expansion during cycling limit its further application. Rational structural designs and specific material selections can be used to create robust volume buffer structures and conductive networks, which consequently contribute to the electrochemical performance of Si materials. Herein, Si particles were encapsulated in the hollow tubular carbon fiber (HT). Further, the porous carbon layer and SnS2 nanosheets were hierarchically assembled on the surface of fibers to create free-standing films with a yolk@multi-shell structure. The unique yolk@multi-shell structure provides sufficient reserved cavities, porous structure, and multiple buffers to significantly resist volume changes. The final electrode is endowed with a multi-dimensional integrated conductive structure by HT and SnS2 nanosheets, which greatly improves the poor conductivity of Si-based electrodes. Finally, the free-standing films can be used directly as anodes, achieving a high specific capacity of 1513.6 mAh g–1 after 100 cycles at 0.1 A g–1. Additionally, the assembled full cell showed 331.4 mAh g–1 after 100 cycles at 0.2 A g–1, which contributes significantly to the advancement of power electronics technology.

Corrosion activities and related accidents are significant issues for marine facilities, leading to considerable economic losses. Waterborne epoxy (EP) coating has been seen as one of the optimal options for corrosion protection due to its stable properties and eco-friendliness (0 g/L volatile organic compounds). Nevertheless, several intrinsic deficiencies require improvement, such as fragile mechanical properties and defects (macro and micro), resulting in the continuous deterioration of comprehensive coating performances. In this work, a novel nanocomposite coating with mechanical enhancement, intelligent self-reporting, and active protection is fabricated by integrating the functionalized and compatible graphene oxide/cerium based metal-organic framework multiscale structure (GO-CeMOF-P/M). Notably, the homogenous dispersion of GO-CeMOF-P/M and its chemical interaction with the polymer matrix effectively reduces the defects resulting from solution volatilizing and enhances the compactness, which boosts the tensile strength (32.1 MPa/8.5%) and dry adhesion force (5.8 MPa) of the coating. Additionally, the controllable responsiveness and release of multiscale nanocomposite within external environments endow intelligent active protection and self-reporting characteristics for the GO-CeMOF-P/M-EP coating, making it especially suitable for a variety of practical marine applications. Furthermore, following immersion of 80 d in the aggressive environment, Zf=0.01 Hz value of GO-CeMOF-P/M-EP coating is 1.2 × 1010 Ω·cm2, which is 164.4 times larger than that of EP coating (7.3 × 107 Ω·cm2), demonstrating remarkably strengthened anti-corrosion ability. Consequently, by offering an intriguing design strategy, the current work anticipates addressing the inherent deficiencies of EP coating and facilitating its practicality and feasibility in real sea environments.
腐蚀活动和相关事故是海洋设施面临的重大问题，会造成巨大的经济损失。水性环氧（EP）涂料因其稳定的性能和生态友好性（挥发性有机化合物含量为 0 g/L）而被视为防腐蚀的最佳选择之一。然而，一些固有的缺陷需要改进，如脆弱的机械性能和缺陷（宏观和微观），导致涂层的综合性能不断下降。在这项工作中，通过整合功能化和兼容的氧化石墨烯/铈基金属有机框架多尺度结构（GO-CeMOF-P/M），制备了一种具有机械增强、智能自报告和活性保护功能的新型纳米复合涂层。值得注意的是，GO-CeMOF-P/M 的均匀分散及其与聚合物基体的化学作用有效地减少了因溶液挥发而产生的缺陷，并增强了致密性，从而提高了涂层的拉伸强度（32.1 兆帕/8.5%）和干附着力（5.8 兆帕）。此外，多尺度纳米复合材料在外部环境中的可控响应性和释放性赋予了 GO-CeMOF-P/M-EP 涂层智能主动保护和自我报告的特性，使其特别适用于各种实际的海洋应用。此外，在腐蚀性环境中浸泡 80 d 后，GO-CeMOF-P/M-EP 涂层的 Zf=0.01 Hz 值为 1.2 × 1010 Ω-cm2，是 EP 涂层（7.3 × 107 Ω-cm2）的 164.4 倍，表明其防腐蚀能力显著增强。因此，目前的研究工作提供了一种引人入胜的设计策略，有望解决 EP 涂层的固有缺陷，促进其在实际海洋环境中的实用性和可行性。

Simultaneously improving the strength and electrical conductivity of conducting metallic materials is of great significance, but it still remains a key challenge as the two properties are often mutually exclusive. In this study, we demonstrate a “<111> oriented fibrous grains with ultra-high aspect ratio” strategy for breaking such a conflict in Cu wire, which relies on the distinctive spatial distribution of grain boundaries and the highly consistent hard orientation to play their respective roles in suffering loading and conducting, thereby enabling a separate optimization of both strength and electrical conductivity. Therefore, a processing route was designed, involving directional solidification followed by large drawing deformation, to successfully construct fibrous grains with an ultra-high aspect ratio in 596.7 and ultra-high <111> texture proportion over 97%, which achieves Cu wire with a remarkable combination of yield strength in 482.3 MPa and electrical conductivity in 101.63% IACS. Finally, the mechanisms for high strength and high electrical conductivity were quantitatively discussed.
