In the dry milling process 2 g of boron powder (H.C. Starck, average size of 800 nm, purity of 95%) and 40 g of tungsten carbide balls (with diameter of 5 mm) were put into the milling jar. The milling jar was maintained in a nitrogen atmosphere using a glove box and vacuum packing to prevent the reaction between the surface of boron particles and oxygen in the atmosphere.

It appears, however, that the rate of ball and liner wear is greater in wet milling so the decision between wet and dry operation is, in cases where the choice is permitted, a matter of balancing the economic gain arising from reduced power demand and increased throughput against the increased cost of replacement of the ball charge and the mill liners and the loss of production during the shut

Then, a high- energy ball milling process was performed at the rotation speed of 350 rpm for 1 h and this process used stainless-steel balls with a ball to powder weight ratio of 1.5:1, and the prepared powder sample was labelled as PM. Pre-alloyed Vanadium alloy powders were firstly prepared by dry grinding method.

Intermediate stops during the ball milling produced a finer aluminum flake powder than non-stop milling for up to 25 h due to cooling of the vial. A larger amount of stearic acid reduces friction between the foil or the balls and vial wall, thus give less milling efficiency, 3 wt. % of stearic acid as additive being verified as the optimum content.

process grinds the powder materials by impact/collision & attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed.
