    15.06.2014· The ball to powder ratio (BPR) is a processing parameter that is frequently used in both mechanical (ball) milling and mechanical alloying. A number of recent studies provided the BPR as a principal milling parameter while neglecting other parameters, such the vial volume, the diameter and quantity of milling balls and the powder mass. In this experiment, different batches of magnesium

    Hydrogen gas is pressurized into the vial (Fig. 9.6 C) together with Mg powders and ball-milling media, using ball-to-powder weight ratio in the range between 30:1 and 100:1. Mg powder particles meet the abrasive and impacting force ( Fig. 9.6 E), which reduce the particle size and create fresh-powder surfaces ( Fig. 9.6 F) ready to react with hydrogen milling atmosphere.
