Summary: The application of an external magnetic field during sintering of ZrO2-based ceramics resulted in lower sintering temperatures and improved ceramic quality, with more perfect crystallographic forms and increased crystallinity compared to sintering without a magnetic field. The presence of a constant magnetic field led to the formation and stabilization of high-temperature phases in zirconium dioxide, as well as improved physical and mechanical characteristics in the resulting oxide ceramics.

Summary: Highly densified Al4SiC4 ceramics with a relative density of 96.1% were prepared using 2 wt% Y2O3 as additives. The presence of Y2O3 during sintering formed a yttrium aluminate liquid phase, promoting densification and anisotropic grain growth. The resulting Al4SiC4 ceramics had a bimodal grain distribution and exhibited superior mechanical properties compared to hot pressed Al4SiC4 ceramics. Pressureless sintering of Al4SiC4 ceramics is significant for the development and practical application of large-sized and complex-shaped Al4SiC4 ceramic parts.

Summary: The study found that the Al content and heat treatment significantly affected the microstructures and mechanical properties of Ti-XAl-2Fe-3Cu alloys. Increasing Al content reduced the average lamellar colony size and thickness of the alloy, while heat treatment increased lamellar thickness and partitioning of Fe and Cu. Increasing Al content slightly increased the strength without changing ductility, while heat treatment slightly reduced strength but increased tensile ductility of the alloys.

Summary: The flash-sintering behavior of Al2O3-GdAlO3-ZrO2 powders with a eutectic composition was investigated in this study. It was found that the flash-sintered bulks consisted of two distinct regions, with a eutectic microstructure observed in the channel region. The formation of the eutectic microstructure was attributed to the localized temperature increase during flash sintering. The resulting eutectic microstructure exhibited high hardness and fracture toughness.

Summary: This study breaks the crystallographic symmetry and induces large and sustainable piezoelectric effects in centrosymmetric materials. The experiment shows the generation of extraordinarily large piezoelectric responses in cubic fluorite gadolinium-doped CeO2-x films, which are two orders of magnitude larger than the responses observed in the presently best-known lead-based piezoelectric relaxor-ferroelectric oxide. This finding provides opportunities to design environmentally friendly piezoelectric materials.

Summary: Electrostriction is a property of dielectric materials where a mechanical deformation is induced in response to an applied electric field. This study reports an engineered electrostriction effect achieved through the controlled interfaces of Gd2O3-doped CeO2 and Er2O3-stabilized delta-Bi2O3 on NdGaO3 substrates. The electrostriction coefficient achieved exceeds the best known materials by three orders of magnitude, and is attributed to the coherent strain from interfacial lattice discontinuity.

Summary: To enhance the oxidation resistance of porous metal components exposed to extreme conditions, a 3D-printed porous 410 L steel support with a novel ceramic multi-coating was developed. The support's simplified morphology with straight channels facilitates wet-chemical coating methods. The multi-coating method combining electrophoretic deposition and infiltration improves the interface between the ceramic and steel. The ceria-based coatings, exhibiting catalytic activity towards H2O and O2, offer both physical and dynamic chemical protection mechanisms. Electro-chemo-mechanical stability and superior corrosion resistance were demonstrated at 750°C in air-3% H2O for 122 hours (0.26 x10(-15) g(2) cm(4) s(-1)).

Summary: Complex oxides with diverse functionalities are crucial for cutting-edge electronics, energy, and information technologies. This review explores how to engineer thermodynamic variables to break the symmetry of centrosymmetric oxides and achieve/improve their electromechanical properties. The mechanisms used to break the inherent symmetry of conventional materials and discover novel applications are discussed. Accessing hidden phases could uncover opportunities for exotic properties like piezoelectricity and pyroelectricity. This review not only reports on engineering nonpolar oxides but also has implications for manipulating polar functional materials for better performance.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
