Nanocrystalline metals prepared by high-energy ball milling

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. This …

Microstructural composite mullite derived from oxides via ...

2004-1-1 · 2004-1-1 · High-energy ball milling had a great influence on phase formation and morphology development of mullite derived from oxide precursors. Mullite phase was formed at 1300 °C in an oxide mixture of Al 2 O 3 and quartz without high-energy ball milling and the mullitization was not complete up to 1500. °C.. After milling for 5 h, the mullitization …
