Abstract
The paper states that in the absence of carbon in the particle bulk the for mation of the nanocrystalline state in alpha-Fe by mecanical milling is not accopanied by the change in structural and magnetic parameters, with the e xception of the increase of the coercivity. In case the source of carbon is present all the changes in magnetic characteristics of nanocrystalline alp ha-Fe, caused by milling time increase, may be explained by carbon segregat ion in boundary zones with the formation of supersaturated solid solutions and Fe3C.
