摘要：

We performed mechanical alloying of Fe and Mg powders with a wide range of compositions and characterized the as-milled alloys with X-ray powder diffractometry, rotating sample magnetometry, density measurements, and Mossbauer spectrometry. Alloys with less than 20 at.% Mg were single phase bcc with enlarged lattice parameters, indicating that Mg atoms were substitutional on the bcc lattice. Mossbauer spectrometry showed these alloys to have large chemical heterogeneties, however. Likewise, it appears that the Mg-rich hcp phase contains some Fe, but the Fe atoms are probably clustered together.
