Ball milling induced abnormal crystallization behavior of an amorphous Fe78Si9B13 alloy

This paper investigates the effect of milling atmospheres on mechanical crystallization of an amorphous Fe78Si9B13 alloy during ball milling. Under an air atmosphere, the amorphous alloy completely transforms into a single α-Fe(Si) phase after milling of 30 h. The crystallization process and products are different from those of thermal crystallization and milling induced crystallization under an argon atmosphere. Moreover, the milling atmosphere has a significant influence on the thermal crystallization of the amorphous phase in the as-milled alloy.
