Effect of BPR on the preparation of Nb-base powder via
For a given milling time of 18 h and rotational speed of 250 rpm ball milling with BPR of 20 1 produces an ultrafine powder with a mean particle size of about 2 μm and a grain size of about 20 nm. A 30 1 of BPR increases the useless collision frequency during ball milling leads to a serious fraying of milling balls.

· As the rotation speed (rpm) increases kinetic energy of the balls increases which in turn shifts the optimum ball size toward a smaller value because the negative influence is alleviated. As the powder loading increases from 1 to 35 g at a given rotation speed (rpm) and ball size the milling efficiency decreases monotonically. This phenomenon is interpreted to be resulted from (1) the increased viscosity and (2) the increased cushion effect
