Summary: The self-healing of grain-boundary cavities by both Au-rich and W-rich precipitates in a high-purity Fe-3Au-4W ternary alloy at 550 degrees C was studied through constant stress creep experiments. The healing kinetics strongly depends on the nucleation time of the cavities, with early-nucleated cavities fully healing and late-nucleated cavities showing slower healing rates.

Summary: In this paper, the fracture behavior and micro-damage evolution in DP600 and DP980 steels were investigated using experimental and numerical methods. The study found that the damage initiation mechanism in DP steels is dependent on the size of ferrite phases, while damage occurs through void formation, initiation of micro-cracks, and the propagation and coalescence of these micro-cracks. The proposed micromechanical FE model can accurately predict the same damage mechanisms as the in-situ tensile test.

Summary: In situ synchrotron radiation X-ray computed tomography was used to study the void nucleation and growth behavior in dual phase steel during uniaxial tensile deformation. Void nucleation primarily occurred in the martensite phase, and the behavior of individual voids was in line with a growth model. Voids elongated during early deformation and dilated isotropically during necking. The average size of the void population increased slowly due to continuous nucleation of new voids.

Summary: This study investigates the ductile fracture of high-strength dual-phase steel under multiaxial stress states at elevated temperatures. Experimental results show that the fracture initiation strain varies with stress triaxiality and temperature. A temperature-dependent plasticity-damage model is calibrated to predict the ductile fracture initiation in the dual-phase steel. This research is important for supporting the performance-based design of steel structures at elevated temperatures resulting from accidental events such as fire.

Summary: Austenitic stainless steels with a bimodal harmonic structure, consisting of fine grain (Shell) around coarse grain (Core), were prepared using powder metallurgy and exhibited improved strength and ductility. X-ray diffraction contrast tomography was used to evaluate the grain shape and location and assess the dislocation density of the Core and Shell structures. The results showed higher dislocation density in the Shell structure compared to the Core structure, indicating localized deformation in the fine grain structure.

Summary: The study investigated the evolution of damage, texture, and strain in additive manufactured 316L stainless steel during in-situ tensile loading using high energy X-rays. It was found that the inhomogeneous distribution of porosity near the surface played a significant role in damage evolution, leading to reduced ductility and final failure in thin-walled AM samples.

Summary: The precipitation strengthening of Cu/NiAl co-precipitates in martensite-austenite dual-phase steels under aging treatment was studied, showing that in the peak aging state, the co-precipitates contribute to an increase in yield strength and uniform elongation. The strengthening mechanisms mainly involve shearing and Orowan looping, with their contributions related to the martensitic phase content.

Summary: This study found that using faba bean protein ingredients can produce meat analogues with a fibrous structure. Increasing the content of faba bean protein isolate (FPI) increases the hardness, gumminess, chewiness, and cutting strength of the meat analogues, resulting in darker color and decreased water absorption capacity. Increased feed water content (FWC) has a weaker and opposite effect on these properties.

Summary: The size and shape of gas bubbles formed in frozen xylem during freezing are crucial for winter embolism formation, with bubbles potentially starting to grow during freezing propagation. Increase in conduit volume seems to lead to larger gas bubble volume, while low water potential and restricted gas escape may increase the risk of embolism formation.

Summary: In this study, a controlled in vitro aortic dissection was performed on notched rabbit aortic segments using tension-inflation tests. Conventional and synchrotron computed tomography were used to observe the macro- and micro-structural morphological changes of the aortic wall during dissection. The study demonstrated that the morphology of the notch and the aorta can be quantified at different steps of the aortic dissection, and the notch geometry correlates with the critical pressure. The method allowed for the real-time visualization of aortic dissection propagation with unprecedented resolution.

Summary: A hierarchical guidance system for 3D nanoscale X-ray imaging is developed, which enables identification, refinement, and tracking of regions of interest within samples beyond the field of view. This approach utilizes rapid multiscale measurements and on-the-fly data processing for immediate feedback on experimental progress. Experimental validation demonstrates the potential of hierarchical guidance for in situ investigations of damage nucleation and deformation kinematics in sheet materials.

Summary: This study aims to investigate the water uptake mechanisms of a two-component epoxy adhesive joint immersed in deionized water. The pore-type defects in the bulk adhesive after the cure cycle were characterized using X-ray mu-tomography. Two different population patterns of defects were identified and analyzed for different thicknesses. Instead of detecting the waterfront, the volume variation and kinetics of pore water filling were accurately determined through optical observations and gravimetric measurements.

Summary: We described the endocranial structures of Hamadasuchus, a crocodylomorph from Morocco, and compared them with other crocodylomorphs. The study identified the cranial bones of Hamadasuchus and explored its paleobiological traits for the first time. The expanded but narrow semi-circular canals and enlarged pneumatization of the skull suggest a terrestrial lifestyle. Further research on the neuroanatomy of terrestrial crocodylomorphs is needed to understand the impact of lifestyle on internal structures.

Summary: The resolution and noninvasiveness of soft-tissue X-ray microtomography (μCT) have made it a widely used three-dimensional imaging method for the study of morphology and development. However, the lack of molecular probes for visualizing gene activity with μCT has remained a challenge. In this study, we successfully apply a method called gene expression CT (GECT) to detect gene expression in developing tissues by combining horseradish peroxidase-assisted reduction of silver and catalytic gold enhancement of the silver deposit. GECT is compatible with various levels of gene expression and sizes of expression regions, and it can be integrated into existing laboratory routines to achieve spatially accurate 3D detection of gene expression.

Summary: The real contact area (AR) is a crucial factor in controlling the frictional and adhesive behavior of a contact interface. Most experimental methods to measure AR have limitations such as requiring at least one transparent solid and only providing information about the interface rather than the bulk deformation. In this study, we propose in situ X-ray Computed Tomography (XRCT) as an alternative method to overcome these limitations, allowing for three-dimensional access to non-transparent contact pairs and providing information about surface deformation. We demonstrate the advantages and disadvantages of XRCT in a smooth contact system, showing its potential for deeper comparisons with existing models of adhesive spherical contacts.

Summary: Porosity is an important property of chondritic meteorites and can be studied using synchrotron radiation microtomography (SR mu CT) and scanning electron microscopy (SEM). Our study on the Bjurbo sample reveals it to be a highly porous and complex medium, with intergranular continuous porosity as the dominant type. The shape of the void volumes affects the connectivity and thermal transport properties, with smaller voids having lower aspect ratios and connectivity. Completely isolated pores are present but have a lower relative frequency compared to continuous porosity.

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.
