Abstract

The disordering process of a B2 Fe-40 Al at% alloy induced by ball milling has been studied from magnetic and structural points of view. The ball milling process involves several steps: loss of long-range order, reduced crystallite size, induced microstrains, loss of short-range order and lattice expansion. These structural changes induce an irreversible transition from a paramagnetic to a ferromagnetic state, which can be observed in the different magnetic parameters studied. © 1999 Elsevier Science B.V.
