    We report on the fluorine diffusivity in nanocrystalline BaF2 and CaF2 as well as in BaF2 CaF2 composites prepared by high-energy ball milling. Mechanical treatment of polycrystalline BaF2 together with CaF2 results in a nanocrystalline composite with an unexpectedly high dc conductivity of about 0.1 mS cm−1

  • Nanocrystalline metals prepared by high-energy ball

    This is a first systematic report on the synthesis of completely nanocrystalline metals by high-energy deformation processes. Pure metals with body-centered cubic (bcc) and hexagonal close-packed (hcp) structures are subjected to ball milling resulting in a decrease of the average grain size to ≈9 nm for metals with bcc and to ≈13 nm for metals with hcp crystal structures.
