| Abstract: | Average grain size of crystalline Ti powder may be yielded down to 12-13 nm
after 24 h milling. Its oxygen and nitrogen contents are very low. Relationship between
hardness and grain size seems to be followed the usual Hall-Petch relationship. |

| Keywords: | ball milling nanocrystalline Ti hardness |
