Abstract  

In the present work, a novel way has been developed to prepare the single–phase nanocrystalline Sm5Co2 alloy. The microstructure and phase constitution were characterized, and it was showed that the nanocrystalline Sm5Co2 alloy has ultra–fine and homogenous nanograin structure with an average grain size of about 10 nm. Moreover, the magnetic and mechanical properties of the Sm5Co2 nanocrystalline bulk were characterized in details, and both properties were enhanced as compared with those of the conventional polycrystalline counterparts.

Key words:  nanocrystalline alloy      Sm–rich phase      magnetic property      mechanical property
