Ball milling of an equiatomic sigma--feV alloy in vacuum
The near-equiatomic FeV alloys are concluded to behave in the same way as the related FeCr alloys when they are ball-milled in vacuum in similar milling conditions. In the stationary state of milling, about half of the iron atoms are contained in an amorphous phase both for sigma-FeCr and for sigma-FeV.

Variables in Ball Mill Operation | Paul O. Abbe®
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.
