Abstract. The ball-milling of pure Fe and Zn elemental powders corresponding to the Г- (Fe 3 Zn 10 ), Г 1- (Fe 5 Zn 21 ), δ- (FeZn 7 ), and ζ- (FeZn 13) compositions yields metastable crystalline phases. This is demonstrated by the peaks observed in the DSC measurements of the different phases. These crystalline phases evolve differently

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
