Summary: Microscopic phase field simulations were performed to study the shearing processes of a periodical array of dual-lobed coprecipitates and monolithic precipitates. It was found that the coupling between the two phases in the coprecipitates forces dislocations to take high energy shearing pathways in both phases that would not occur in monolithic forms. The presence of coprecipitates generally increases the resistance to dislocation shearing and leads to higher strength levels.

Summary: The study focused on the micro hardness and micro structure of Al-Sc alloy and Al-Sc-Zr alloy with different scandium percentages. It was observed that there was only slight difference in hardness during the initial aging stage of the developed alloys, while the Al-Sc-Zr alloy maintained peak hardness for a longer period, showing better thermal stability. Analysis also indicated the inhibition of precipitate growth through precipitation of Zr in the initial aging stage. TEM results revealed the formation of two different sized precipitates in the Al-Sc-Zr alloy after reaching peak hardness.

Summary: The study investigates precipitation behavior in different alloy conditions, revealing that materials with a low volume fraction of η/δ phase and a high proportion of primary γ' precipitates will form γ'' phase due to excess Nb. Spherical γ' precipitates with disc-shaped γ'' precipitates at γ' interfaces were observed. The enrichment of phase forming elements during discontinuous coarsening of η/δ plates leads to heterogeneous nucleation of γ' at the η/γ interface, with thin η plates embedded in δ phase in grain boundary pinning precipitates also confirmed. These results demonstrate the conditions under which certain primary phases form and how the consumption and redistribution of phase promoting elements trigger the formation of secondary phases.

Summary: This study investigates the microstructural evolution and the effects of discontinuous precipitation (DP) and ordering on the age-hardening behavior in Au-20Ag-30Cu ternary alloy. Experimental observations reveal that DP forms at grain boundaries consisting of alternating α1 and α2 phases, while L12-type AuCu3 ordered phase with nanometric spherical particles forms at grain interior and within the lamellar α1 phase of DP. Both DP and L12-type AuCu3 nanoprecipitates show growth with elevated aging temperature. DP at grain boundaries is found to have a detrimental effect on overall age-hardening, while the L12-type AuCu3 nanoparticles effectively impede the movement of dislocations to enhance age-hardening.

Summary: This study uses atom probe tomography to characterize high-quality Cu(In,Ga)Se-2 (CIGS) films on flexible substrates and reveals the unique characteristics of grain boundaries (GBs) in CIGS and the correlations between matrix elements and alkali dopants. The study identifies various compositional fluctuations at GBs, with [Cu-poor and Se/In,Ga-rich] GBs being more common than [Cu-rich and Se/In,Ga-poor] ones. In addition, the study finds anti-correlations between Cu and other matrix elements that are associated with the degree of alkali segregation at GBs.

Summary: This study evaluated the performance of different EAM and 2NN-MEAM potentials in predicting fracture behavior in single-and bicrystalline tungsten. The results showed significant underestimation of surface energies and variation in unstable stacking and twinning fault energies by most EAM potentials. Additionally, the EAM potentials were unable to reproduce the TS curves derived from DFT, leading to qualitative differences in the fracture behavior. The new 2NN-MEAM potential best reproduced fracture-relevant material properties and exhibited consistency with experimental results.

Summary: This paper investigates the deformation and fracture of Al reinforced with carbon nanotubes (CNTs) through atomistic simulations. The study finds that the interaction between CNTs and Al is weak, allowing CNTs to easily slide inside the Al matrix under tensile loading. However, when CNTs are geometrically fixated inside Al, they can increase the fracture stress and induce plastic deformation.

Summary: This study investigates the effect of off-stoichiometric composition on the fracture behavior of NiAl alloy using microbending tests. The results show that small variations in composition lead to drastic changes in fracture behavior. Ni-rich NiAl exhibits a gradual decrease in fracture toughness and plastic energy dissipation with Ni-concentration, while Al-rich NiAl shows a concentration-independent low fracture toughness and no plasticity.

Summary: Industrial upscaling often leads to a different coating microstructure compared to laboratory prototypes. In this study, we observed a crystallographic reorientation towards a basal texture in physical vapor deposited MoS2 coatings after wear testing. This favorable reorientation can improve the friction properties of the coatings, making them comparable to ideal chemical vapor deposited MoS2 single crystals.

Summary: Solute segregation at grain boundaries in magnesium alloys with multiple substitutional elements has a strong impact on various material characteristics. This study investigates the compositional inhomogeneity of six different grain boundaries using experimental and simulation techniques. The results reveal that the solute concentration of Nd in Mg varies between 2 and 5 at.%, and this variation is observed for different grain boundary orientations and within the grain boundary plane. Correlated atomistic simulations suggest that this inhomogeneous segregation behavior is caused by local atomic rearrangements within the grain boundaries.

Summary: Using atomistic simulations, this study investigates the atomic-scale mechanisms of motion of zonal dislocations in Laves phases. Two types of synchro-Shockley dislocations with different properties are identified, and it is demonstrated that the nucleation and propagation of kink pairs are energetically favorable for their motion. The roles of vacancy hopping, interstitial shuffling, and nonsequential atomic shuffling are also investigated, providing insights into the plastic deformation induced by zonal dislocations and related phases.

Summary: This study provides a microscopic understanding of the topological anisotropy in silica glass, induced by mechanical loads, using novel analysis methods on glasses generated by molecular dynamics simulations. The anisotropy originates from the preferred orientation of SiO4 tetrahedra in the silica network, which can be controlled through different mechanical loading modes. The findings elucidate the relation between deformation and the resulting anisotropic structure, providing important insight for the design of oxide glasses with tailored materials properties.

Summary: Synchro-Shockley dislocations, as zonal dislocation, play a crucial role in the plasticity of Laves phases at high temperatures. The motion of these dislocations involves localized transition events, and their activation volumes contribute to the temperature and strain rate sensitivity of the Peierls stress. However, the thermally activated behavior of synchro-Shockley dislocation motion is not well understood. This study investigates the transition mechanisms of these dislocations at different shear and normal strain levels, and reveals that the motion of synchro-Shockley dislocations is sensitive to shear, but requires thermal assistance for shear-insensitive events, indicating their inhibition at low temperatures.

Summary: We propose a physically motivated strategy for generating training sets for transferable machine learning interatomic potentials. The strategy involves systematically exploring all possible space groups in random crystal structures and deforming the cell shape, size, and atomic positions. The resulting potentials are unbiased and applicable to bulk defect studies without incorporating any defect structures in the training set. We use this approach to construct transferable potentials for pure magnesium that accurately reproduce the properties of hexagonal closed packed (hcp) and body centered cubic (bcc) polymorphs.

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.
