Structural evolution of titanium powder during ball milling …
Nitrogen and oxygen diffused into titanium to form a solid solution and the Ti powder picked up much more nitrogen and oxygen for the sample milled in a closed vial than that milled in an open vial at the initial stage of milling. A titanium oxynitride with an fcc structure was produced by ball milling Ti in a closed vial for a longer time.

How to Choose the Right Tool for Milling Titanium
Milling titanium is like milling other hard-to-machine metals in that a small increase in cutting speed can lead to a big increase in edge wear. Milling titanium is different from other metals because of the risk of heat build-up. Thanks to the metal's low thermal conductivity, overly aggressive milling may even pose a risk of combustion. ...
