Powder Production Technologies

Brittle materials can be pulverised in ball mills, hammer mills or attritor mills to form powders. Intermetallics and ferro-alloys are commonly processed this way. As variants on this approach, Hydride-Dehydride (HDH) titanium alloy powders can be produced by reacting the alloy in solid form with hydrogen to form a brittle hydride, which can
