Nanocrystalline metals prepared by high-energy ball

Sep 01, 1990 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

Sep 01, 1990 Abstract. 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.

Nanocrystals by high energy ball milling ScienceDirect

May 01, 1992 It has been shown recently that nanocrystalline materials can also be synthesized by high energy ball milling of elemental powders (5,6,7), intermetallic compound powders (5,8,9), or immiscible powders (10,11,12). Fecht et al (6) developed nanocrystalline structures in various elemental bcc and hcp metal powders by ball milling.

Nanocrystalline CaF2 particles obtained by high-energy

Apr 01, 2006 Applying the same methods, the results could be compared with those of mechanochemically synthesized CaF 2 samples, prepared for the first time in this study by high-energy ball milling. The applied methods indicate that the mechanically treated samples become, under the applied conditions, nanocrystalline. Unexpectedly, the mechanochemically
