概要

• 論文の詳細を見る

• A high-pressure phase of TiO2 with a baddeleyite-type related structure has been synthesized via very rapid heating-cooling under energetic Nd-YAG laser pulse irradiation of the Ti target in oxygen ambient. Spherical nanoparticles transformed martensitically into baddeleyite-type and then $\alpha$-PbO2-type structures with accompanied transformation twinning, shearing and shape change into ellipsoid upon electron irradiation. The relatively large particles followed the same transformation path yet with alternative lattice correspondence and additional multiple deformation twinning of the baddeleyite type.
