Abstract
The microstructure and disaccommodation of the magnetic susceptibility for micro- and polycrystalline Fe6.5%Si samples (with initially diffe rent order) aged at 973 K were studied. It is stated that ageing the s ample in which initially the short range order occurrs, leads to the a ppearance of the Fe,Si structure. This is accompanied by the increase of the disaccommodation amplitude. The isochronal disaccommodation cur ves were decomposed into five elementary processes and their activatio n energies were calculated.
