Strong fiber–metal interfacial bonding is essential for achieving reliable strain transfer and sensing performance in embedded optical fiber sensors for structural health monitoring. However, conventional embedding approaches, such as ultrasonic additive manufacturing and laser-assisted additive manufacturing, often introduce interfacial voids and incomplete bonding that compromise both mechanical integrity and sensor functionality.

In this study, the effect of sintering temperature on the phase composition, density, microstructure, and mechanical properties of multidoped zirconia-toughened alumina (MZTA) ceramics containing multidoped zirconia (Zr0.90(Y, Ce, Ca, Mg)0.10O2) was investigated. The samples were fabricated using a conventional ceramic processing and sintered at temperatures ranging from 1400 to 1600 °C for 5 h. X-ray diffraction and whole-powder-pattern fitting (WPPF) analysis showed that, regardless of the sintering temperature, the samples consisted predominantly of t-ZrO2 and Al2O3 phases, with a minor (0.7–2.8 wt. %) amount of m-ZrO2 detected at certain temperatures.
Type 430 stainless-steel specimens with large sulfide inclusions were fabricated by mixing MnS or TiS2 powder with Type 430 stainless-steel powder and consolidating the mixtures by spark plasma sintering. MnS addition produced MnS inclusions, whereas TiS2 addition produced complex inclusions comprising TiS2, TiN, and (Mn,Ti)S. Microscale polarization of individual inclusions in 0.1 M Na2SO4 yielded dissolution-potential ranges of MnS (0.2–0.7 V) < (Mn,Ti)S (0.5–1.0 V) < TiS2 (1.0–1.8 V).
BaTiO3 is an important ferroelectric ceramic that leads progress across various industries. Spark plasma sintering is a technique used to obtain highly densified ceramics with fine grain sizes. Thermal treatment is often necessary after spark plasma sintering to restore the ceramics’ insulating behavior. The literature on BaTiO3 is extensive, with reported permittivity values ranging from a few thousand up to several hundred thousand with the latter typically referred to as colossal permittivity.
Bore anti-erosion coatings are capable of increasing the service life and reliability of gun barrels, highlighting the critical requirement for improvement and evaluation of the interfacial bonding performance. In this study, a quantitative method is proposed to characterize the interfacial bonding performance of the chromium/gun steel, and thereafter used to analyze the effects of magnetron sputtering parameters on the interfacial bonding.
A series of Ti/Cr nanoscale multilayer coatings with a fixed total thickness of 1.5 μm but varying individual layer thicknesses h (5 nm, 10 nm, 20 nm, 50 nm, 100 nm, and 150 nm) were prepared by adjusting magnetron sputtering parameters. The microstructure and morphology of the coatings were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM), indicating that their microstructures transitioned from fine equiaxed grains to coarse columnar grains as the increasing of h.

Véhicules électriques, développement des énergies renouvelables, explosion des data centers et essor de l’intelligence artificielle : les besoins en électricité évoluent rapidement. Dans ce contexte, l’électronique de puissance est confrontée à un double défi : convertir et gérer davantage d’énergie, tout en limitant les pertes et l’encombrement des systèmes.
Porous media play a critical role in active-cooling thermal protection systems due to their unique microstructural characteristics.

To address the softening and limited oxidation and water-vapor corrosion resistance of Si bond coats at ultra-high temperatures, Si and Si–15 mol% HfO2 (denoted 15HS) composite bond coats were deposited on pressureless sintered SiC substrates by air plasma spraying (APS). Their phase evolution, cross-sectional microstructure, and failure mechanisms were examined after 20–200 h at 1623 K in dry oxygen and in a 90% H2O–10% O2 environment. In dry oxygen, a SiO2 thermally grown oxide (TGO) layer formed on the Si coating surface, cracked and spalled with time, and the coating thinned progressively.
LOS ANGELES, CALIFORNIA, October 21, 2026 - California Nanotechnologies Corp. ("Cal Nano" or the "Company") is pleased to announce that it has signed an amendment to its existing Santa Ana facility lease to support its manufacturing capacity expansion. The lease amendment includes an additional 15,500 square feet of adjacent space, representing an approximate 80% increase to the Company’s existing (19,500 square feet) footprint, and provides access to increased electrical current capacity to power its core technologies and other equipment.

3D graphene networks offer significant potential for enhancing the mechanical and functional performance of metal matrix composites. In this study, sucrose was employed as a solid carbon precursor and homogeneously mixed with nickel (Ni) powders to enable in-situ graphene formation through rapid thermal annealing (RTA). This approach eliminates the need for conventional graphene dispersion techniques and enables a uniform and efficient incorporation of graphene within the metal matrix.
AlCoCrFeNi₂.₁ high-entropy alloy (HEA) particle-reinforced 6061Al composites were fabricated by spark plasma sintering (SPS) at different temperatures to investigate the evolution of the particle/matrix interface and its influence on wear behavior. Increasing the sintering temperature accelerated elemental diffusion but also promoted the formation of Al₁₃Co₄, Al₈Cr₅ and AlCr₄ intermetallic compounds. At 550 °C, a continuous diffusion/interfacial reaction layer about 10 μm thick formed at the interface, accompanied by more uniform elemental distribution and relatively stable metallurgical bonding.
How a layered boride behaves depends on both its atomic structure and the way it is made. A comprehensive review of MAB phases connects those factors with reported mechanical and functional properties, including oxidation-assisted crack healing and magnetocaloric behavior. It also examines how certain parent compounds yield two-dimensional MBenes. The review describes current limits in synthesis, product identification and testing as researchers explore structural ceramics and functional devices.
The challenge in developing ultrafinegrained composites is suppressing grain coarsening during hightemperature service. Herein, we report a strategy for preparing (La0.5Ba0.5)B6-ZrB2 composites with ultrafine grains and superior stability via sintering aids and selection of a densification temperature compatible with the service temperature.
The Cr2AlC MAX phase was successfully prepared by co-sputtering Cr-Al alloy target and graphite target at low temperature by magnetron sputtering method. Deposition temperature (100-400°C) was investigated, examining its effects on MAX phase formation, film structure, corrosion resistance, and friction properties. The results indicated that when the deposition temperature reached 300°C, the Cr2AlC MAX phase began to form in the film, and its crystallization tendency became more pronounced with further increasing temperature.
CoCrRu targets for perpendicular magnetic recording required high relative density and fine grains, which were difficult to achieve by conventional routes. This study investigated targets fabricated by spark plasma sintering (SPS) from powders milled for 3 h, 14 h and 25 h, as well as those produced by arc melting (AM). The optimal milling time was determined to be 14 h based on particle refinement and phase homogenization.

Il existe un mécanisme qui empêche certains alliages de se briser à -253 °C. Son secret vient d’être percé par un groupe de chercheurs internationaux qui étudient maintenant ses possibles applications.
In this work, Porous copper foam samples were fabricated by a space-holder technique with water-atomized copper powder and sodium chloride (NaCl) particles in weight fractions ranging from 10 to 35 wt%. The powders were mechanically mixed at a 10:1 ball-to-powder ratio and 150 rpm for 2 h. The effects of space-holder content on the physical, mechanical, tribological, and electrochemical performance were systematically investigated. Increasing the NaCl fraction precisely controlled the total porosity, from 39.15% to 57.76%, and reduced the bulk density from 5.452 to 3.785 g/cm³. XRD and SEM analyses confirmed a single-phase FCC copper matrix and a structural transition from isolated pores to a highly interconnected open-cell network.
Ultra-high-temperature ceramics (UHTCs), including TiC, Ti11B₂, and Zr11B₂, show great potential for plasma-facing components due to their excellent high-temperature properties prior to irradiation. However, their response to neutron irradiation remains insufficiently understood, limiting robust assessment of their viability for fusion energy applications.
