Summary: Aluminum-silicon is a binary eutectic system where the solid solubility of aluminum in silicon is limited. The addition of alkaline earth elements to the eutectic phase mixture of Al-Si leads to a change in morphology from planar to three-dimensional with facets on (111) planes. In this study, first-principles calculations are used to explain the origin of these morphological variations and the influence of interatomic interactions between aluminum, silicon, and inoculant atoms.

Summary: In this study, the effects of minor Ti, Mn, Cr, Zr, and Er additions on cast Al-Zn-Mg-Cu alloys were investigated. The addition of Ti significantly refines the ingot grains, while Mn and Cr additions reduce impurities and form specific phases. The joint addition of Ti, Mn, Cr, Zr, and Er creates a bulk composite phase. The alloy with the joint addition of these elements exhibits the highest hardness due to collaborative strengthening effects.

Summary: The study found that AA7075 alloy in different heat treatment states exhibits different behaviors during stress relaxation, with alloys in peak-aged condition showing the highest stress drop and plastic strain change. As stress relaxation cycles repeated, the decrease in activity of mobile dislocations led to a decrease in stress drop, and the relationship between grain orientation hardness and lattice strain affected the stress relaxation effect.

Summary: Using the experimental-simulation combination method based on the split Hopkinson tensile bar test, the fracture behavior of 2A12-T4 aluminum alloy compact tensile specimens was investigated in this study. By comparing with experimental results, the numerical approach was validated, and the influence of specimen thickness was analyzed. It was found that the J-integral curves increase exponentially with time, and specimens of different thickness exhibit similar variation patterns. With increasing thickness, the dominant factor changes from the plane stress area to the plane strain area, and the J-integral value first increases and then decreases to a constant value. The percentage of the plane strain area in the total thickness was derived.

Summary: Strengthening of metals by incorporating nano-scale coherent twin boundaries has been a significant breakthrough in recent years. In this study, the contribution of twin boundaries in nano-lamellar lightweight Ti-Al alloys to deformation and fracture behavior is investigated using atomistic simulations. The results show that nano-scale lamellae effectively improve fracture toughness and crack growth resistance, and the lamellar size controls the crack tip mechanisms. A critical lamella thickness is identified, and above this thickness, crack tip events are primarily dislocation-based plasticity. Below the critical thickness, a decline in fracture toughness is observed and the crack tip propagation mechanisms become quasi-brittle in nature.

Summary: The effect of pre-deformation and post-ageing on the age hardening response and tensile properties of an Al-Cu alloy has been studied. It was found that moderate pre-deformation and specific temperature conditions can significantly improve the yield strength and uniform elongation of the alloy. Dislocations and precipitates play a major role in determining the strength of the alloy, while hard barriers can initiate void and deteriorate plasticity.

Summary: The incorporation of Mo(2)TiC2 improved the strength, ultra-high ductility, and fracture toughness of Mo alloys. The main reasons for the superior ductility in Mo-Mo2TiC2 alloys were identified as high relative density, grain refinement, high lowangle grain boundaries (LGBs) proportion, and strain hardening rate. Additionally, the ultra-high toughness of Mo-Mo2TiC2 alloys was attributed to plastic deformation capacity, crack deflection, particles pullout, and secondary cracking.

Summary: DP steels with a 'Thomas-fibers' type platelet martensite morphology exhibit significantly larger cracking resistance compared to corresponding equiaxed microstructures, offering a new path to optimize fracture toughness without compromising strength and/or changing the chemical composition. The superior cracking resistance is shown to originate from a remarkable resistance to damage nucleation related to the alignment of the platelets upon deformation and from their small size.

Summary: Alloying with Sn is an effective strategy to inhibit hydrogen evolution and dendrite growth of Zn metal anodes in rechargeable aqueous batteries. In-situ monitoring shows that Sn alloy electrodes have significantly lower hydrogen evolution compared to pure Zn electrodes, while also providing favorable Zn nucleation sites for more uniform Zn deposition. The Zn-Sn alloy electrodes demonstrate improved cycling performance in terms of plating/stripping cycles and depth of discharge, making them a practical solution for stabilizing Zn metal electrodes in rechargeable aqueous batteries.

Summary: Rechargeable Zn batteries are widely studied as safe and environmentally friendly alternatives to Li-ion batteries. The use of a 3D porous Zn anode can suppress Zn dendrite growth and improve electrode kinetics, but it also exacerbates the hydrogen evolution reaction (HER). To address this issue, a polytetrafluoroethylene (PTFE) coating is applied on the porous Zn as an artificial solid-electrolyte interphase (SEI), effectively inhibiting HER and maintaining Zn plating kinetics. The combination of porous morphology and artificial SEI layer results in improved performance, including dendrite-free Zn plating/stripping for up to 2000 hours and extended cycling in the Zn||V2O5 cell.

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.
