Ni-Al-V based alloys possess superior creep resistance at higher temperatures because of the sluggish interdiffusion of constituent elements within the L12-Ni3(Al, V) matrix. In this study, intrinsic diffusion coefficients of Ni, Al and V in quasi-binary Ni3Al1-xVx (x = 0, 0.125, 0.25, 0.5) were quantified based on a first-principles calculation for elucidating the effect of V concentration on the coarsening behavior of L12 domains. From the results of the estimated formation energies, migration energies and activation energies, it was found that intrinsic diffusion coefficients of Ni and Al are decreased by the addition of V, while intrinsic diffusion coefficient of V remains two or three orders of magnitude smaller than them. Such a suppressed diffusion of Ni and Al by V addition well explains the experimentally obtained lower coarsening rates of L12 domains in Ni3Al0.58V0.42 and Ni3Al0.48V0.52 alloys.

The mechanical properties of Ni3Al1_xVx alloys (0.4 L12 stems from the stagnation of V diffusion in the L12 matrix, but the mechanism of such a "diffusion blocking effect" has not been elucidated. In this study, a first-principles calculation was employed to quantify diffusion coefficients of Al and V in stoichiometric Ni3Al and V-doped Ni3Al from the intrinsic formation energies, migration energies and acti-vation energies required for their diffusion. The calculated diffusion coefficient of V was three orders of magnitude smaller than that of Al, and thus the shorter diffusion distance of V than the requisite diffusion length for the retention of D022 was found to be responsible for the diffusion blocking effect observed in the Ni3Al1_xVx alloys.

<p>In this paper, the properties of the barium titanate (BT)/polyvinylidene fluoride (PVDF) composites were controlled by the self-assembly of the BT secondary particle groups. The self-assembled BT/PVDF composites of 5–20 vol.% BT were prepared with the difference in the viscosity of polyethylene glycol (PEG) of dispersants involved in the self-assembly process. The multifractal properties and dielectric properties of the self-assembled BT/PVDF composites were investigated with controlling by the formation of the self-assembled BT secondary particle groups. The dielectric constant (ε′) increased with an increase in the average secondary particle area (<i>S</i>) of the BT particles. The <i>S</i> increased with an increase in the viscosity of PEG; whereas, the ε′ decreased with the increase in viscosity. The multifractal analysis indicated that the distribution of self-assembled BT secondary particle groups was affected by PEG viscosity. The sample with PEG1000 had aggregates with a BT/PVDF/BT heterointerface, the sample with PEG20000 had agglomerates with a BT/BT interface, and the sample with PEG2000 had both, aggregates and agglomerates. The BT/PVDF/BT heterointerface in the BT aggregates played an important role in improving the dielectric properties of the BT/PVDF composites. Overall, the viscosity of the dispersant affected the self-assembly process as well as the ε′. It was suggested that the multifractal properties and dielectric properties were controlled by the self-assembly of the BT secondary particle groups.</p>

本研究では、従来手掛けてきたオングストロームビーム電子回折実験に関連した新たな解析技術の開発を行い、リチウムイオン電池のアモルファス負極材の解析にこれらの技術も応用することで、これまでに得られなかったアモルファス電池材の局所構造の情報を得られるようになった。さらに、実際に充放電を行ったアモルファス材についても解析を行い、充放電過程における局所構造の情報を得られるようになった。今後、リチウムイオン電池の充放電機構解明のため、さらに微視的な詳細を得る予定である。
