摘要：

The crystallisation, structure and magnetic properties of Sm-Co powders prepared by mechanical alloying were studied. High values of remanent magnetisation of up to 0.8 M(s) were obtained in isotropic nanocrystalline samples after heat treatment. The remanence decreased with increasing crystallite size while the coercivity increased. The presence of the SmCo5 phase resulted in an increase of the coercivity. A maximum energy product of 18 MGOe was measured in optimally treated SM12.5Co87.5.
