Mg50Co50 alloys were prepared by mechanical alloying. The formation of a body-centered cubic (bcc) structure was confirmed by X-ray and electron diffraction. This bcc alloy comprises nanometer-scale crystals, and absorbed H, with a capacity of 2.67 mass% at 258 K. The mechanism of the fabrication and enhanced hydrogen storage properties of the Mg50Co50 bcc alloy were investigated and compared with common Mg-based alloys. (c) 2009 Acta Materialia Inc.

Synthesis of NaBH4 as a hydrogen carrier from hydrated borax using a Mg-Al alloy

Yongyang Zhu, Hao Zhong, Liuzhang Ouyang, Jiangwen Liu, Hui Wang, Huaiyu Shao, Min Zhu

Summary: In this study, an energy-saving and cost-efficient process for the (re)generation of NaBH4 was reported by ball milling hydrated borax with a Mg-Al alloy under ambient conditions. The introduction of abundant and readily available Al can increase air stability of the reducing agent, and a high yield up to 85.2% could be achieved by using Mg17Al12 due to its hardness and brittleness.

Diffusion of hydrogen in the body centered tetragonal hydride phase of the V-H system controlled by multiple substitutional metal elements

Kohta Asano, Shigenobu Hayashi, Yumiko Nakamura, Etsuo Akiba

Summary: The diffusion and site occupation of hydrogen in the monohydride phase (β phase) of the V1-x-yCrxMoy-H (x + y <= 0.15) system were investigated using proton nuclear magnetic resonance. It was found that the substitution of both Cr and Mo offsets the change in the activation energy for hydrogen diffusion, while our previous study showed that Cr increases the activation energy and Mo decreases it. The diffusion behavior can be explained by the dimension of the interstitial sites and the weighted mean atomic radius of the substitutional metal elements, independent of their affinities for hydrogen and the lattice strain.

Diffusion of boron in an amorphous iron-boron alloy

Takumi Hamaguchi, Ryusuke Nakamura, Kohta Asano, Takeshi Wada, Takeyuki Suzuki

Summary: A thin-film diffusion couple consisting of amorphous iron-boron (a-FeB) alloys with different ratios of stable isotopes of B was prepared using a sputtering technique, and the interdiffusion profiles were obtained by secondary-ion mass spectrometry to evaluate the diffusion coefficient of B in a-FeB at temperatures ranging from 533 K to 653 K. The activation energy and pre-exponential factor for diffusion were determined to be 1.51 eV and 3.0 x 10-8 m2 s-1, respectively. Comparison with reported data showed that boron is the fastest diffusing element in a-FeB, and the activation energy for B diffusion is similar to that for the crystallization of iron in alpha-FeB, suggesting that B diffusion is the rate-determining process.

Completely Elastic Deformation of Hydrogenated Ta Thin Films

Lars J. Bannenberg, Larissa Blom, Kouji Sakaki, Kohta Asano, Herman Schreuders

Summary: Nanostructured metal hydrides have a crucial role in a hydrogen economy, as the nanostructuring or confinement of these materials significantly affects their structural and functional properties. We demonstrate that confining tantalum as a thin film extends its solubility limit, suppressing the phase transition observed in bulk upon hydrogenation. The continuous elastic deformation of the tantalum unit cell with unequal lattice constants and angles ensures volumetric expansion in the out-of-plane direction, resulting in superb performance as a hysteresis-free optical hydrogen sensor over a wide hydrogen pressure/concentration range.

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.
