Ball milling induced crystallization of amorphous

2007-3-25  Ball milling of melt-spun Fe 90 Zr 10 ribbons in a planetary ball mill (AGO-2) induces their crystallization into supersaturated α-Fe(Zr) grains. The crystallization degree of the amorphous phase increases with increasing milling time, with a fully crystalline state being obtained after 30 min at a milling speed of 1000 rpm.
