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.

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。
