摘要：
Iron and chromium powder mixtures were elaborated by mechanical alloying (MA) from 0 to 30 h of milling times and over the whole concentration range. Mossbauer spectrometry was performed in order to characterize the influence of the nanostructure on magnetic properties, especially of the intergranular zone. Mossbauer results at 300 K show that the properties of MA FeCr powders alloying over the whole concentration range can be interpreted taking into account two contributions: a contribution associated with the FeCr nanograin core, which is very close to the FeCr bulk alloy with the same composition and contribution associated with the weakly magnetic disordered intergranular zone, created by gases dissolved during milling.
