Summary: In this paper, the interactions between mechanically alloyed Mg6Pd1-xAgx alloys and hydrogen were studied. The structures of the alloys were analyzed using X-ray diffraction (XRD), which confirmed the presence of a single Mg6Pd-type phase for samples with up to x=0.5 silver concentration. The kinetics of hydrogenation process and the properties of synthesized hydride were investigated using a Sievert-type sorption analyzer and differential scanning calorimetry (DSC) with thermogravimetric analysis (TGA). The results showed that partial substitution of palladium with silver improved the hydrogen sorption kinetics compared to pure Mg6Pd intermetallic phase, but resulted in lower hydrogen content. The influence of silver on the decomposition kinetics was also observed.

Summary: High-energy synchrotron x-rays are used to track the evolution of grain-averaged lattice reorientation and stress-state in Ti-7Al during cyclic loading. Accumulating plastic strain is observed even when the sample did not exceed its elastic limit. The largest changes in lattice orientation and stress state occur after the first cycle, followed by a slower evolution in subsequent cycles. The variation of axes for lattice reorientation is highly dependent on the maximum resolved shear stress and activation of different slip systems.

Summary: The interaction between Mg17Al12 precipitate and low-angle grain boundaries in Mg-Al alloys was investigated using molecular dynamics simulations. The precipitate was found to be sheared by grain boundaries with a rotation angle of 9 degrees or larger, but not sheared with a rotation angle smaller than 8 degrees. An analytical model based on Eshelby theory was proposed to explain this behavior, and it showed good agreement with the simulation results. The critical shear of the grain boundary was found to be related to the aspect ratio of the precipitate.

Summary: A recently developed strategy for promoting abnormal grain growth during cyclic heat treatment has the potential to manufacture single crystals with a size of several centimeters. However, there is still a lack of detailed understanding of the elementary mechanisms involved in this kind of abnormal grain growth. This study provides time resolved insights into the interplay of these mechanisms for the first time, using in situ synchrotron high energy X-ray diffraction analysis. The results not only deepen our understanding of abnormal grain growth, but also lay the foundation for improving the efficiency of the cyclic heat treatment process and obtaining even larger single crystals.

Summary: This study visualizes a new three-dimensional grain boundary sample using laboratory-based X-ray diffraction tomography and determines the percolation threshold of grain boundaries in the thermodynamic limit. Comparison with past simulations shows good agreement. The study also investigates the percolation threshold of triple junction lines and finds them to be lower than that of grain boundaries. These findings have implications for the design of failure-resistant materials.

Summary: Alloying additions in magnesium can modify common basal textures during recrystallization based on their solid solubility and precipitation behavior. The type and level of solute segregation in grain boundaries play a key role in controlling the growth behavior. Further research can advance current alloy design strategies by tweaking the solute concentration in the solid solution.

Summary: In this study, the deformation behavior of the plastic inorganic semiconductor Ag2S was investigated using in situ neutron diffraction at different temperatures. The results showed that at room temperature, the distribution of lattice strain among different crystallographic plane families may be responsible for the significant work-hardening behavior in bulk Ag2S. At 453 K, Ag2S undergoes a phase transformation from monoclinic to body-centered cubic phase, with a stress plateau and subsequent rehardening. The deformation mode of bulk Ag2S at the initial stage is likely due to the migration of silver ions, and as strain increases, it resembles the behavior at room temperature, leading to rehardening.

Summary: Multi-pass rolling can improve the strength and ductility synergy in ultrafine-grained AZQ310 alloy sheet by reducing grain boundary segregation. The as-extruded alloy has high yield strength but poor elongation due to the presence of ultra-fine grains and co-segregation of Al/Zn atoms at grain boundaries. In contrast, after multi-pass rolling, the sheet exhibits higher yield and ultimate strength, as well as improved elongation along the rolling direction.

Summary: The precipitation of a stable quasicrystalline i-phase has been observed in a Mg-6Zn-3Al magnesium alloy, which may be the first discovery of a stable i-phase in this alloy. The dissolution of i-phase at grain boundaries leads to precipitation in the Mg-matrix during cooling. Nucleation characteristics, phase transformation, and interface morphology were investigated.

Summary: This study analyzed the GND densities of five selected fine-grained magnesium samples. Different fatigue-loading conditions were applied to three samples at 0 degrees C, one experienced quasi-static tensile loading at 0 degrees C, and one represented the as-rolled state. The results provide new insights into the deformation mechanism of fine-grained magnesium at 0 degrees C, showing significant increases in GND density for the tested samples compared to the as-rolled sample, especially for the sample with low-maximum applied stress.

Summary: This study utilized Na-23 MRI to directly observe the microstructural growth of sodium in an all-solid-state cell, revealing a porous dendritic morphology which was confirmed through various methods. The significantly larger T-2 contrast for dendritic growth compared to bulk metal electrode is attributed to increased sodium ion mobility within the dendrite. Na-23 T-2 contrast MRI of metallic sodium provides a clear and routine method for observing and isolating microstructural growth, complementing current techniques for analyzing dendritic growth in all-solid-state cells.

Summary: The strain fields of deformation twins in an age-hardened duplex stainless-steel were studied using HR-EBSD. The study parameterised the 2D elastic strain field at the twin tip using J-integral and decomposed it into mode I and mode II stress intensity factors. It was found that the elastic field described by KI increased with twin thickness, while the in-plane shear field described by KII relaxed when the load was removed.

Summary: A methodology is presented to impose micromechanical constraints by finding the equilibrated stress field closest to a non-equilibrated stress field through an optimization problem. The method uses the Hodge decomposition of a symmetric matrix field to extract the equilibrated part of a general field, and involves high-order derivatives that can be efficiently calculated in Fourier space. The method is applied to filter non-equilibrated stress fields in synthetic and experimental data, with the largest corrections near grain boundaries.

Summary: Zinc oxide tetrapods possess remarkable functional and mechanical properties and can be applied in various fields including nanoelectronic and optoelectronic sensing, functional composites and coatings, and energy harvesting and storage. Through assembly into high porosity macroscopic ceramic framework structures, they can serve as versatile templates for fabricating other foam-like materials with multiple scales. In this study, we investigated the three-dimensional structure of low density interconnected zinc oxide tetrapod networks using high resolution X-ray computed tomography. In-situ observations during mechanical loading revealed the heterogeneous development of anelastic strain (damage) during compression and the homogeneous elastic recovery during unloading. Individual tetrapods were observed to deform through arm rotation to accommodate strain.

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.
