Herein, a series of bioactive glasses with a composition based on SiO2Na2OCaO-P2O5-Bi2O3, doped with either manganese (Mn) or copper (Cu), or a combination of both have been developed. The aim was to create a biocompatible, bioactive material with a photothermal (PT) response for potential use in bone cancer treatment. UV/vis/NIR spectroscopy indicated that the addition of Cu to the glass resulted in a broadband absorption of around 800 nm, while Mn showed an absorption band of around 500 nm. Photoluminescence (PL) spectroscopy, which was performed by exciting the specimen using a 750 nm beam, revealed an emission at 823 nm for all glass compositions, but with varying intensities. When exposed to an 808 nm laser (5 W/cm2), the glass samples exhibited temperature rising, with the sample containing both Mn and Cu, showing the highest absorption peak, reaching 204 °C after 5 min. The degradation rate of the glass in a phosphate-buffered saline (PBS) solution was influenced by the presence of Mn and Cu. Cytotoxic assessment on osteoblast-like cells showed that the presence of Mn promoted cell proliferation by over 20 % after 24 h, but when irradiated with an 808 nm laser, the viability of cells decreased by nearly 60 % due to heat ablation. Finally, the glass sample demonstrated in vitro bioactivity through the formation of a hydroxyapatite layer on its surface when immersed in simulated body fluid.
在此,我们开发了一系列生物活性玻璃,其成分以 SiO2Na2OCaO-P2O5-Bi2O3 为基础,掺杂了锰(Mn)或铜(Cu),或两者的组合。其目的是创造一种具有光热(PT)反应的生物相容性生物活性材料,以用于骨癌治疗。紫外/可见/近红外光谱显示,在玻璃中添加铜会产生约 800 纳米的宽带吸收,而锰则显示出约 500 纳米的吸收带。光致发光(PL)光谱分析是通过 750 纳米光束激发试样来进行的,结果显示所有玻璃成分都在 823 纳米处发光,但发光强度各不相同。当暴露在 808 纳米激光(5 W/cm2)下时,玻璃样品温度升高,其中含有锰和铜的样品吸收峰值最高,5 分钟后达到 204 °C。玻璃在磷酸盐缓冲盐水(PBS)溶液中的降解率受锰和铜的影响。对成骨细胞进行的细胞毒性评估显示,24 小时后,锰的存在促进了 20% 以上的细胞增殖,但用 808 纳米激光照射时,由于热烧蚀,细胞的存活率降低了近 60%。最后,将玻璃样品浸入模拟体液后,其表面会形成羟基磷灰石层,从而显示出体外生物活性。

In-situ reaction-generation self-healing superior antioxidation layer induced by Al-Y sol-gel film on the AISI304 steel Al-Y 溶胶凝胶膜在 AISI304 钢上诱导原位反应生成自修复高级抗氧化层

In this study, an Al-Y sol-gel film is prepared on the AISI304 steel and its effect on the high temperature oxidation resistance is evaluated by the cycle oxidation at 900 ℃ in the air. The resulting intact oxide layer, composed of (Al, Cr)2O3 and MnCr2O4 phases, effectively slowing down the oxidation rates at 900 ℃. The general cracks in the sol-gel film during the oxidation process are found to be self-healed by a growing spinel MnCr2O4 phase from the substrate, attributed to its low Gibbs free energy and the sufficient Cr source from the adjacent substrate. Furthermore, the oxide layer originates from the interaction between sol-gel film and the substrate which enhances the binding between the oxide layer and the substrate. Thus, it could be confirmed that a self-healing superior antioxidation layer is generated on the surface of AISI304 steel through an in-situ reaction induced by the Al-Y sol-gel film during high-temperature oxidation procedure.
本研究在 AISI304 钢上制备了 Al-Y 溶胶凝胶膜,并通过在空气中进行 900 ℃ 循环氧化评估了其对高温抗氧化性的影响。生成的完整氧化层由(Al, Cr)2O3 和 MnCr2O4 相组成,可有效减缓 900 ℃ 下的氧化速率。在氧化过程中,溶胶凝胶膜上出现的一般裂纹可通过基底上生长的尖晶石 MnCr2O4 相进行自修复,这归功于其较低的吉布斯自由能和邻近基底上充足的铬源。此外,氧化层源于溶胶-凝胶薄膜与基底之间的相互作用,这种相互作用增强了氧化层与基底之间的结合力。因此可以确认,在高温氧化过程中,Al-Y 溶胶凝胶膜诱导的原位反应在 AISI304 钢表面生成了自愈性极佳的抗氧化层。

Fracture behavior of brittle particulate composites consisting of a glass matrix and glass or ceramic particles with elastic property mismatch 由玻璃基体和玻璃或陶瓷颗粒组成的弹性性能不匹配的脆性颗粒复合材料的断裂行为

The aim of this work is two-fold: i) elaborating dense and transparent inorganic glass composites with improved fracture properties, and ii) testing the theoretical analysis proposed in [1] and based on Poisson's ratio mismatch. Particulate composites, consisting of glass or ceramic particles embedded in a soda-lime-silica glass matrix, were synthesized and their fracture behavior was studied by means of the Single-Edge Precraked Beam (SEPB) and Double Cleavage Drilled Compression (DCDC) methods, using in situ experiments with X-ray tomography where possible. An important effect of the T-stress on the fracture toughness (KIc) was observed in the case of DCDC experiments. KIc is increased by about 40 % by incorporating 7 vol. % amorphous silica beads or SrAl2O4:Eu,Dy ceramic particles (SAED) with a 40 μm mean particle size. It is suggested that toughening results from the crack front trapping and pinning at particle sites and from the tortuous crack path in the case of a-SiO2 particles, and from the contribution of the intrinsic fracture surface energy of the ceramic particles, which are cleaved by the propagating crack, in the case of the SAED particles. The thermally induced stress field is believed to play a major role in the case of a-SiO2 particles. Two glass grades possessing Young's moduli similar to the one of the matrix but much larger Poisson's ratios were used to produce glass beads. However, the incorporation of these latter beads in the matrix was found to have a minor incidence on the fracture behavior.
这项工作有两个目的:i) 制备具有更好断裂性能的致密透明无机玻璃复合材料;ii) 测试 [1] 中提出的基于泊松比失配的理论分析。我们合成了玻璃或陶瓷微粒嵌入钠钙硅玻璃基体中的微粒复合材料,并通过单边预裂梁(SEPB)和双裂钻孔压缩(DCDC)方法对其断裂行为进行了研究,在可能的情况下使用 X 射线断层扫描进行现场实验。在 DCDC 实验中观察到 T 应力对断裂韧性(KIc)的重要影响。通过加入 7 体积百分比的无定形二氧化硅珠或平均粒径为 40 μm 的 SrAl2O4:Eu,Dy 陶瓷颗粒 (SAED),KIc 增加了约 40%。研究表明,a-SiO2 颗粒的增韧源于裂纹前沿在颗粒位置的捕获和钉扎,以及曲折的裂纹路径;而 SAED 颗粒的增韧源于陶瓷颗粒固有的断裂表面能,它被扩展的裂纹劈开。热诱导应力场被认为在 a-SiO2 颗粒中起主要作用。生产玻璃珠时使用了两种玻璃牌号,它们的杨氏模量与基体的杨氏模量相似,但泊松比要大得多。然而,在基体中加入后一种玻璃珠对断裂行为的影响很小。

In this study, the Charpy impact test was performed for mechanically introducing cracks in A533B steel. Then, in situ weak-beam scanning transmission electron microscopy (WB-STEM) annealing tests were performed from room temperature to 600 °C. A wide area surface polishing method that did not require chemical polishing or resin-filling process for bulk specimens were developed for microsampling a 200 nm thin film. The film was sampled from the strain site at the crack tip (EBSD-KAM value: 2.7°) via Focus ion beam-scanning electron microscopy (FIB-SEM), i.e., the inhomogeneous plastic deformation zone of dislocation density above 2.5 × 1016 /m2 formed by Mn precipitates. In isochronous annealing process imaging, the dynamic behavior of dislocations was successfully visualized using movie files with a spatial resolution of 0.4 nm/pixel and a temporal resolution of 1s/frame via WB-STEM. Results revealed thermal relaxation of local strain as high density dislocations deformed into new subgrain boundaries via the geometrically necessary dislocation network at control temperatures from 500 °C to 550 °C.

This paper investigates the elastic properties of the model Fe-Cr-C alloys, specifically focusing on M23C6 and M7C3. The study uses in-situ synchrotron X-ray data during tensile deformation to determine the individual elastic characteristics of the matrix and iron/chromium carbides. The experimental results obtained from in-situ X-ray diffraction (XRD) are compared to the elastic constants of carbides that were reported in previous studies and derived using density function theory (DFT). The appropriate elastic constants for M23C6 and M7C3 were selected based on the self-consistent code executing with reported elastic constants. The directional elastic modulus and Poisson's ratio of iron/chromium carbides are calculated, and the anisotropy of the elastic constants is evaluated using the XRD lattice deformations under loading. The elastic modulus of carbide varies with the volume fraction of carbide in the effective medium. The study finds that the hexagonal structure is more probable than orthorhombic structure for M7C3 due to well-matched estimations of the directional elastic modulus and Poisson's ratio obtained from in-situ XRD data and the self-consistent calculations. In-situ XRD analysis of elastic behavior of each diffraction can be used to demonstrate the elastic constants of carbides and shows potential for obtaining precise elastic constants by integrating with self-consistent modeling and DFT.
本文研究了铁-铬-碳合金模型的弹性特性,特别侧重于 M23C6 和 M7C3。研究利用拉伸变形过程中的原位同步辐射 X 射线数据来确定基体和铁/铬碳化物的个别弹性特性。通过原位 X 射线衍射 (XRD) 获得的实验结果与之前研究报告中使用密度函数理论 (DFT) 得出的碳化物弹性常数进行了比较。M23C6 和 M7C3 的适当弹性常数是根据自洽代码与报告的弹性常数的执行结果选出的。计算了铁/铬碳化物的定向弹性模量和泊松比,并利用加载下的 XRD 晶格变形评估了弹性常数的各向异性。碳化物的弹性模量随有效介质中碳化物的体积分数而变化。研究发现,由于从原位 XRD 数据和自洽计算中获得的方向弹性模量和泊松比估计值非常匹配,M7C3 的六方结构比正方结构更有可能。对每种衍射的弹性行为的原位 XRD 分析可用于证明碳化物的弹性常数,并显示了通过与自洽建模和 DFT 相结合获得精确弹性常数的潜力。

Thermostable Al alloys have been a consistent focus for decades, mainly adopting alloying strategy to improve thermostability of precipitates. In this work, it was found that matrix defects controlling could be a new way to improve thermal stability of Al alloys. Three alloys with composition of Al-4.1Cu-2.1Mg-0.3Mn but varied dislocation densities and grain sizes were prepared, and their thermal stability at 200 °C were investigated by identifying hardness vs. holding time curves. It revealed that the alloy with high dislocation density and small grain size showed poor thermal stability. Because dislocation and grain boundary provided accelerated diffusion channels for Cu and Mg atoms, leading to rapid growth of S’(Al2CuMg) precipitates, and the growth rate was a liner function of square of dislocation density ρ2 or square of grain size reciprocal 1/d2 according to data fitting. A “dislocation affected zone” model was proposed to explain the diffusion phenomenon.
几十年来,热稳定性铝合金一直是人们关注的焦点,主要采用合金化策略来提高析出物的热稳定性。这项研究发现,控制基体缺陷可能是提高铝合金热稳定性的一种新方法。研究人员制备了三种合金,其成分为 Al-4.1Cu-2.1Mg-0.3Mn,但位错密度和晶粒大小各不相同。结果表明,位错密度高、晶粒尺寸小的合金热稳定性较差。由于位错和晶界为铜和镁原子提供了加速扩散的通道,导致 S'(Al2CuMg)析出物快速生长,根据数据拟合,生长速率是位错密度 ρ2 的平方或晶粒尺寸倒数 1/d2 的平方的衬函数。提出了 "位错影响区 "模型来解释扩散现象。

Grain boundary sensitization kinetics of cold-rolled Al–Mg alloys 冷轧铝镁合金的晶界敏化动力学

As super-saturated solid solutions of Al-Mg, 5XXX series aluminum alloys are susceptible to sensitization via intergranular precipitation of the anodic β-phase, which promotes intergranular corrosion, exfoliation and stress corrosion cracking under environmental conditions. This study presents important updates to a Johnson–Mehl–Avarami–Kolmogorov (JMAK) type model for low-temperature sensitization, correlating the intergranular corrosion response to impingement of locally sensitized regions surrounding discrete β-phase grain boundary precipitates. It is demonstrated that the sensitization response of these alloys can be approached as a combination of two independent contributions: the geometric configuration of grain boundaries passing through the microstructure that are most prone to sensitization, and the rate that these boundaries sensitize due to the formation of the β-phase. This allows for the large sensitization response variations found between nominally identical materials produced by different suppliers, which originate due to a lack of constraints within current cold-rolled plate tempers, to be removed as a sample-dependent linear scaling factor that is separate of the rate kinetics. The JMAK model describes the kinetics of 5xxx series sensitization with excellent accuracy across all data available in the literature. The results of the model imply that sensitization at environmental temperatures proceeds via a site-saturated process, with the β-phase forming on a set density of preferential nucleation sites. It is shown that site-saturation allows for extension of the JMAK model to non-isothermal aging profiles and supports a diffusion pathway dominated by pipe diffusion to the interface followed by precipitate growth via the collector plate mechanism.
作为铝镁的过饱和固溶体,5XXX 系列铝合金很容易通过阳极 β 相的晶间沉淀而敏化,从而在环境条件下促进晶间腐蚀、剥离和应力腐蚀开裂。本研究对约翰逊-梅尔-阿瓦拉米-科尔莫戈罗夫(JMAK)型低温敏化模型进行了重要更新,将晶间腐蚀反应与围绕离散β相晶界析出物的局部敏化区域的撞击联系起来。研究表明,这些合金的敏化反应可作为两个独立因素的组合来处理:穿过微观结构的晶界的几何构造最容易发生敏化,以及这些晶界因形成 β 相而敏化的速度。这样就可以消除不同供应商生产的名义上相同的材料之间存在的巨大敏化反应差异,这种差异是由于当前冷轧板温度缺乏限制造成的,它是与速率动力学无关的、与样品有关的线性比例因子。JMAK 模型描述了 5xxx 系列敏化的动力学过程,在所有文献数据中都非常准确。该模型的结果表明,在环境温度下,敏化是通过位点饱和过程进行的,β 相在一定密度的优先成核位点上形成。研究表明,位点饱和允许将 JMAK 模型扩展到非等温老化剖面,并支持以管道扩散到界面为主,然后通过集流板机制沉淀物生长的扩散途径。

The adoption of additive manufacturing (AM) technologies, particularly Laser Powder Bed Fusion (LPBF), has been rapidly increasing in industries requiring high precision and complex geometries. Despite its advantages, LPBF faces challenges related to defects that affect material quality, with spatter formation being a significant concern. Spatters – tiny particles ejected during the printing process – can adversely affect the final product’s integrity by altering surface roughness and contributing to defects. This study introduces a comprehensive approach to predict the ejection velocity and direction of spatter particles using a suite of machine learning (ML) algorithms, including Random Forest, Gaussian Process Regression, Support Vector Machine, Regularized Linear Regressions, Gradient Boosting Trees, and Neural Networks. Our analysis reveals that the Neural Network model outperforms others, achieving prediction accuracies of 97.58% for spatter velocity and 88.22% for ejection direction, thus offering a substantial improvement in understanding and controlling spatter-related defects in LPBF processes. The practical implications of these predictions are profound, enabling manufacturers to adjust AM parameters in real time to minimize defects and enhance product quality. This study not only fills a gap in the current literature by providing a detailed comparative analysis of multiple ML algorithms for spatter ejection prediction but also paves the way for future research into real-time monitoring and control systems in AM.
在要求高精度和复杂几何形状的行业中,增材制造(AM)技术,尤其是激光粉末床熔融(LPBF)技术的应用迅速增加。尽管 LPBF 具有诸多优势,但它也面临着与影响材料质量的缺陷有关的挑战,其中飞溅物的形成是一个重大问题。飞溅物--印刷过程中喷射出的微小颗粒--会改变表面粗糙度并导致缺陷,从而对最终产品的完整性产生不利影响。本研究介绍了一种综合方法,利用一套机器学习(ML)算法,包括随机森林、高斯过程回归、支持向量机、正则化线性回归、梯度提升树和神经网络,预测飞溅颗粒的喷射速度和方向。我们的分析表明,神经网络模型优于其他模型,对飞溅速度的预测准确率达到 97.58%,对喷射方向的预测准确率达到 88.22%,从而大大提高了对 LPBF 工艺中飞溅相关缺陷的理解和控制能力。这些预测具有深远的实际意义,使制造商能够实时调整 AM 参数,从而最大限度地减少缺陷,提高产品质量。本研究通过对用于飞溅喷射预测的多种 ML 算法进行详细比较分析,不仅填补了现有文献的空白,还为未来 AM 实时监测和控制系统的研究铺平了道路。

Carbon steel bars are critical in steel-reinforced concrete structures, and their corrosion can lead to significant deterioration. This research explored the passive layer formation on different carbon steel microstructures using a high throughput approach. Thermomechanically treated steel bars with three distinct microstructures, i.e., martensite in the outer layer, bainite in the middle, and pearlite in the center, were vertically cut and immersed in the simulated concrete pore solution. Scanning electrochemical microscopy was employed to study the formation of the passive layer, the kinetics of the passivation, and the effective rate constant of the species inside the solution on each microstructure. Results showed that the formation of the passive layer is a time-dependent process, and passivation was influenced by the local microstructure. Martensite demonstrated superior passivation behavior compared to pearlite and bainite.
碳钢筋在钢筋混凝土结构中至关重要,其腐蚀会导致结构严重老化。本研究采用高通量方法探索了不同碳钢微结构上被动层的形成。经热力学处理的钢筋具有三种不同的微观结构,即外层为马氏体、中间为贝氏体、中心为珠光体。采用扫描电化学显微镜研究了每种微观结构上被动层的形成、钝化动力学以及溶液内部物种的有效速率常数。结果表明,被动层的形成是一个随时间变化的过程,钝化受局部微观结构的影响。与波来石和贝氏体相比,马氏体的钝化性能更优。

Corrosion and hydrogen permeation resistance of pulse electrodeposited Zn coatings were correlated with coating micro-texture and strain. The maximum and minimum corrosion resistance were noted for D6F75 (duty cycle 60; frequency 75 Hz) and D8F25 (duty cycle 80; frequency 25 Hz), respectively. The D6F75 coating exhibited a higher fraction of low-energy low-angle grain boundaries (LAGBs) and a preferred texture of (31¯2¯1) whereas the D8F25 coating exhibited comparatively low LAGBs fractions and(21¯1¯0) orientation. High resistance to hydrogen permeation exhibited by the D6F75 coating was attributed to hydrogen trapping within the coating, which reduced the micro-strain within the coating and diminished the hydrogen concentration gradient, thereby promoting greater surface recombination.
脉冲电沉积锌镀层的耐腐蚀性和抗氢渗透性与镀层的微观纹理和应变有关。D6F75(占空比 60;频率 75 Hz)和 D8F25(占空比 80;频率 25 Hz)的耐腐蚀性分别最大和最小。D6F75 涂层的低能低角晶界(LAGBs)比例较高,优先纹理为(31¯2¯1),而 D8F25 涂层的 LAGBs 比例相对较低,取向为(21¯1¯0)。D6F75 涂层表现出的高抗氢渗透性归因于涂层内的氢截留,这降低了涂层内的微应变,减小了氢浓度梯度,从而促进了更大的表面重组。
