Summary: Using a multi-phase-field approach in computer simulation, the study systematically analyzes the roles played by particle size and thermodynamic and kinetic factors of interfaces in different stages of internal pore shrinkage in a three-particle green body. It is demonstrated that particle rigid body translation promotes neck growth and pore rounding and shrinkage, while rotation does not contribute to pore shrinkage.

Summary: Through a comprehensive numerical study, it was found that nickel depletion in the fuel electrode of SOEC can lead to nickel phase coarsening, consequently reducing the electrochemical performance of the electrode. Increasing the wettability of the nickel phase can effectively mitigate the reduction of active reaction sites caused by nickel coarsening.

Summary: The study found that under strictly humid conditions, while the presence of steam gradient leads to nickel redistribution, the formation and diffusion of Ni(OH)(2) do not significantly change the nickel coarsening rate. It is concluded that other competing mechanisms must be responsible for the observed nickel redistribution and enhanced coarsening under humid conditions.

Summary: Metal-supported solid oxide fuel cells have the advantages of quick startup, low cost, and excellent robustness. This study investigated the effect of thermally driven elemental diffusion on the morphology and electrochemical performance of Ni-Fe alloy supported Ni-yttria stabilized zirconia anode and yttria stabilized zirconia electrolyte film. It was found that elemental diffusion can enhance the sinterability of the layers and promote the formation of an electrocatalytically active alloy structure.

Summary: The kinetics of phase coarsening in a dense binary, two-phase system were theoretically studied and existing relations were recovered and generalized. Equations for particle size distribution and coarsening were rigorously derived. An interesting finding is that the scaling exponent, m, for the kinetics of phase coarsening at ultra high volume fractions takes values in the range 2 < m < 3, depending on the precise volume fraction of the dispersed phase, when varied over the narrow range 0.9 < V-V < 1. The particle size distributions derived in this study depend on volume fractions, which is different from Wagner's particle size distribution for interface-reaction-controlled phase coarsening. The current work substantiates that the kinetics of phase coarsening at ultra high volume fractions exhibits a blend of both interface-reaction-controlled and volume diffusion-controlled phase coarsening.

Summary: A novel multiphase field model was used to analyze the phase coexistence of tetragonal and rhombohedral phases in Pb-free BZT-40BCT. The study predicted metastable coexistence between the two phases, with domain microstructures exhibiting faceted domain walls and curved T-R phase interfaces near the polymorphic phase boundary. The miniaturization of domain structures near the boundary is due to low interfacial energies and a pinning effect from a large metastable phase fraction.

Summary: In this study, a phase-field fracture model is developed to investigate crack growth in solid oxide cells (SOCs). The simulation results show that work-zone cracking dominates under thermal cycling in electrolyte-supported SOCs, while only minor mechanical degradation occurs in hydrogen-electrode-supported SOCs. Under redox cycling, through-cracking of yttria-stabilized zirconia (YSZ) in the hydrogen electrode and electrolyte layers dominates. Crack-mitigation strategies, such as reducing the porosity in the hydrogen electrode support layer and synchronizing thermal strain, are suggested.

Summary: This research investigates the influence of Ni particle coarsening on the performance of solid oxide fuel cell (SOFC) using a transient multi-physical field model. The study finds that high operating temperature and an increase in the ratio of steam to carbon accelerate Ni particle growth and deterioration of SOFC performance. Increasing the diameter of yttria-stabilized zirconia (YSZ) particles and improving the Ni phase fraction can slow down the growth rate of Ni particles and the attenuation of current density. By combining artificial neural network (ANN) and genetic algorithm (GA), the study provides a framework for fast prediction and optimization of SOFC performance.

Summary: This paper analyzes the effect of particle size distribution on the quality of electrophoretic deposition coating. The results show that increasing the fine powder fraction can improve the density of the coating and slow down the growth rate of oxides, leading to a decrease in surface resistance. Samples prepared with admixed powder exhibit the lowest resistivity. Post-test analysis indicates no diffusion of chromium through the fabricated layers, indicating the reliability of the protective barrier.

Summary: Solid oxide electrolysis cells (SOECs) are highly efficient and flexible energy conversion devices, but their long-term operation is limited by the degradation of Ni/yttria-stabilized zirconia (YSZ) fuel electrodes, which is recognized as one of the main causes for cell performance loss. This study investigates the microstructure evolution of Ni/YSZ electrodes after long-term operation in a CO/CO2 atmosphere. Results show significant loss of Ni in the active electrode and increased Ni fraction in the support layer after 1000 hours of operation at -1 A cm(-2). Ni coarsening was also observed. Similarly, Ni migration away from the electrode/electrolyte interface occurs during long-term CO2 electrolysis.

Summary: This study investigates the heat balance and degradation process of solid oxide electrolysis cell (SOEC) at the system level, comparing the Levelized Cost of Hydrogen (LCOH) at different locations under three scenarios: heat integration, super grid connection, and SOEC development. It is found that SOEC generates additional ohmic heat and reduces the external heat demand significantly after degradation. Through heat integration, the LCOH is reduced to $3.60 per kg, further lowered to $2.59 per kg with the super grid connection. SOEC development breaks the trade-off between current density and degradation, resulting in an LCOH of $2.18 per kg. By 2035, green hydrogen is expected to achieve an LCOH of $1.40 per kg, surpassing gray hydrogen.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: The limited slip systems of magnesium (Mg) and its alloys hinder their wide applications. By conducting tensile straining experiments, researchers discovered a rate-dependent transition in the dislocation mechanisms of Mg alloys. At high strain rates, glissile dislocations dominate, while easy-glide dislocations dominate at low strain rates. Abundant glissile dislocations do not necessarily improve ductility.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.

Summary: A novel testing system for miniature specimens is designed to characterize the plastic response of materials for which conventional full-size specimens cannot be extracted. The system has an automated operation process, which reduces the damage to specimens caused by manual handling and improves the stability of the test results. The experiments show that the miniature specimens extracted from stainless steel and aluminum have high reproducibility, and the results are consistent with those of conventional-sized specimens. A correction procedure is provided to consider the influence of surface roughness and heat-affected zone caused by wire EDM.
