Summary: In light water nuclear reactors, waterside corrosion of the cladding material results in the formation of hydrogen, which precipitates into brittle hydride particles in zirconium cladding. A phase field model has been developed to predict the observed hydride morphology and identify the mechanisms responsible for the stacking of nanoscale hydrides in zirconium grains. The model challenges some previously proposed mechanisms for hydride reorientation under applied stress.

Summary: Porosity can heavily influence the properties of nuclear-grade graphite, and electron tomography is able to visualize the sub-micron pores in three dimensions. This research demonstrates the 3D structure of both native and irradiation-induced nano-cracks in graphite, as well as the unique characteristics of graphite such as pore structure. The technique could also be useful for molecular dynamic simulations and experimental techniques related to irradiated graphite and other nuclear porous carbon-based materials.

Summary: A chemo-mechanical phase-field model is developed to capture the complex phase segregation processes in NaxFePO4 (0 < x < 1), along with the structural changes during charging/discharging. The model constructs a multi-well potential for NaxFePO4 for the first time and investigates the microstructure evolution during sodiation and desodiation processes. Results suggest that the formation of an intermediate phase can reduce stress and improve mechanical stability, leading to better battery performance.

Summary: The domain structure and energy-storage performance of Pb(Zr1-xTix)O-3 (x ≤ 0.1) single crystal and thin-film systems are investigated. It is found that by controlling the ratio of domain wall coefficients and the strain, the energy-storage performance of antiferroelectric materials can be improved, leading to higher energy-storage density and efficiency.

Summary: Coarsening of the basketweave alpha + beta microstructure in Ti-6Al-4V during thermal cycling is driven by multiple dissolution and precipitation transformations instead of conventional Ostwald ripening. This study reveals that the vanishing of alpha plates continues during repeated thermal cycling through two mechanisms, which are related to the Gibbs-Thomson effect. The influence of cycling frequency and total duration on the coarsening transformation is also detected. Long cycling duration leads to severe coarsening, while the final coarsening of alpha plates is almost independent of the cycling frequency.

Summary: Adiabatic shear band (ASB) is an important failure mechanism observed in metals and alloys under impact loading, with a two-dimensional propagating feature. However, in-situ characterization of temperature-deformation fields during ASB formation is challenging due to the small scales involved. In this study, a plane-array infrared imaging system and microspeckle-based digital image correlation technique were used to obtain the two-dimensional features of ASB evolution in titanium alloy specimens. Experimental characterization and simulation results were used to analyze the thermo-mechanical aspects of ASB formation.

Summary: Perovskite-structured praseodymium aluminum oxide (PrAlO3) is a promising new neutron-absorbing material matrix with high stability. By solid-phase reaction synthesis and adding a liquid phase sintering aid, high-density perovskite phase PrAlO3 ceramics with good thermophysical and mechanical properties can be prepared. These materials have great application prospects as neutron-absorbing nuclear materials based on rare earth ions.

Summary: Ti42Al6Nb 2.5CxTa alloys were prepared to investigate the effects of Ta content on the microstructure and mechanical properties. Increasing Ta content led to the increase of gamma and Ti2AlC phases, decrease of alpha 2 phase, and refinement of lamellar colony size. Tensile tests showed an improvement in strength and strain with increasing test temperature, with higher Ta content alloys exhibiting better high temperature properties.

Summary: This review focuses on the research progress of utilizing small-scale mechanical property tests to evaluate the degradation of mechanical properties caused by ion irradiation. It highlights the lack of consistency and reliability in the evaluation of irradiation effects of materials, particularly ion-irradiated materials, due to unclear or debated rationality and accuracy of existing data analysis models, such as size-dependence. Establishing a standardized method is highly demanded to quantitatively bridge the gap between micro- and macro-scale mechanical properties of ion irradiated materials.

Summary: The phase-field method, a powerful and popular approach in materials science, has been widely used to predict mesoscale microstructure evolution. This paper provides a historical review of the origin, basic idea, and development of phase-field models. The focus is on classical and state-of-the-art applications in China, including phase transformations, crack propagation, and fractures. The future development directions of the phase-field method are also discussed.

Summary: The microstructures of the as-cast alloys changed from FCC phase to a mixture of FCC and BCC phases, and then to a mixture of BCC phase and Ti-containing intermetallic compound with increasing Ti content. The increasing Ti content also led to higher macrohardness of the alloys, with Al0.5CrFeNi2.1Mn0.8Ti0.5 showing excellent comprehensive compressive properties.

Summary: W-Mo-Cu alloy was fabricated by large current electric field sintering at a low temperature of 950 C. The nanoscale phases formed at the boundaries of W, Mo, and Cu phases were observed through transmission electron microscope (TEM) images. X-ray diffraction patterns and inverse fast Fourier transform (IFFT) analysis confirmed the existence of defects and atom diffusion during the sintering process.

Summary: In this study, an efficient uncertainty propagation and quantification technique based on probability measures and deep generative unsupervised representative machine learning method is proposed for microstructure-based design of thermal conductivity of materials. By using deep Variational AutoEncoder (VAE), the correlations between the material/process parameters and the thermal conductivity of microstructures are identified. The findings emphasize the advantages of high-throughput phase-field modeling and generative deep learning for linking PSP and inverse microstructure-centered materials design.

Summary: A microstructure-dependent model of radiation-induced segregation (RIS) has been developed to investigate the accumulation of species and phase stability in irradiated LiAlO2. The model takes into account the thermodynamic and kinetic properties of defects and describes the spatial and temporal distributions of defects and chemistry. The RIS model has shown the ability to assess the effect of thermodynamic and kinetic properties of defects on the segregation and depletion of species and to explain the phase stability observed in irradiated LiAlO2 samples.
