Study of the enhancement of the magnetic properties of Fe[sub 70]Al[sub 30] in the order-disorder transition.

The order-disorder transition produced by ball milling in the intermetallic Fe[SUB70]Al[SUB30] has been systematically studied by x-ray diffraction, calorimetry, and Mössbauer experiments. These techniques show a monotonous transformation that ends after 6 h of milling. In the transition, the lattice parameter increase amounts to 0.7% and there is a large enhancement of the alloy's magnetism. [ABSTRACT FROM AUTHOR]
