摘要：
Magnetic properties of coarse-grained and of nanocrystalline mechanically alloyed Fe-Cr-Sn alloys are investigated. The average magnetic moment, the coercive field and the Curie temperature decrease when the Sn content in both kinds of alloys is increased. Their respective values are found to be smaller in the case of mechanically alloyed samples. This fact is due to the difference between nominal and matrix compositions of coarse-grained alloys.
