Quasicrystal and related phase particles were successfully dispersed in wrought-processed Mg-7.6 wt.% Zn-3.9 wt.% Al alloy with homogeneous and fine-grained structures. This rare-earth-free alloy showed high strength and ductility balance, which was superior to that of the well-known quasicrystal phase dispersed in Mg-Zn-RE alloys, with a weak texture and a reduction of mechanical asymmetry in yield strength.

Naomi Nishimura, Kazumasa Masaki, Wei Tan, Reona Iimura, Hiroaki Kobayashi, Kei Nishikawa, Toshihiko Mandai, Hidetoshi Somekawa, Yoichi Tominaga

Summary: To improve the cycle performance of Mg metal batteries, a polymer coating (PSTFSI-Mg) was applied on the surface of spinel-type MgMn2O4 cathode. The polymer coating promoted electron transfer between particles, as confirmed by transmission electron microscopy. Density functional theory calculations revealed that the polymer reduced the energy gap between the valence band maximum of MgMn2O4 and the highest occupied molecular orbital level of the electrolyte, thus suppressing electrolyte degradation.

Fabrication of Li anode metal via bulk mechanical property analysis

Hidetoshi Somekawa, Kei Nishikawa, Taku Moronaga, Takahito Ohmura

Summary: Two types of lithium metals with different average grain sizes were successfully produced through extrusion process and rapid molding process. The hardness of the metals was found to be influenced by grain size, decreasing with a finer grained structure, which is contrary to the trend observed in other light-weight pure metals. The fine-grained Li metal exhibited a large strain rate dependence and unusual behavior, attributed to the contribution of grain boundary sliding to deformation. Additionally, the fine-grained Li metal showed better electrochemical characteristics in terms of over-potential and voltage response during charging and discharging operations.

Induced kink boundary in Mg-Y-Zn alloy by tube-shape forming

Hidetoshi Somekawa, Motohiro Yuasa

Summary: The secondary formability and the effect of shape application on induced kink boundaries in Mg-9at.%Y-6at.%Zn alloy were investigated through experimental and numerical studies. A tube-shaped alloy without any cracks was successfully formed with kink boundaries associated with the applied shear strain. Numerical results showed a substantial shear strain at the contact region, but with an opposite shear direction after tube formation, indicating the possibility of de-kinking behavior. Additionally, the formed alloy exhibited higher hardness by 30 Hv compared to the un-processed alloy, and the correlation between kink density and hardness was consistent with literature results on wrought-processed Mg-Y-Zn alloys.

On the co-nucleation of adjoining twin pairs at grain boundaries in hexagonal close-packed materials

Darshan Bamney, Laurent Capolungo

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.

Sharp/diffuse antiferroelectric-ferroelectric phase transition regulated by atomic displacement ordering

Bing Han, Zhengqian Fu, Guoxiang Zhao, Xuefeng Chen, Genshui Wang, Fangfang Xu

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.

Guowei Zhou, Yuanzhe Hu, Zizheng Cao, Myoung Gyu Lee, Dayong Li

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.

Relating the combinatorial materials chip mapping to the glass-forming ability of bulk metallic glasses via diffraction peak width

Ze Liu, Cai Chen, Yuanxun Zhou, Lanting Zhang, Hong Wang

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.
