Milling Process Of Fe

Möss Study of the Ball Milling Disordering Process of ...

Structural changes during ball milling of ordered Fe 50 Al 50 intermetallic compounds were studied. X-Ray diffraction allowed the computation of a Long Range Order parameter (LRO) which dropped to zero after a short milling time. The initial B2 ordered structure gradually transforms into a disordered BCC structure, with a final crystallite size of about 25 nm.

On the contrary, during the milling process with MEG no reaction was observed since the Fe (0) content after milling was above 90 % in all cases. In the absence of embrittlement, iron behaves like a soft and ductile metal and it flattens plastically under the effect of the grinding media forming the observed flakes.
