Partially crystallized amorphous alloys SmCo/Fe and SmCo/FeCo with nanocrystalline α-Fe and α-(Fe,Co) grains distributed in the amorphous SmCo matrix were synthesized by mechanical alloying of a mixture of SmCo5and α-Fe and FeCo powders. The crystallization process and kinetics of these amorphous alloys upon annealing have been investigated. For SmCo/Fe amorphous alloy, with the increase of the annealing temperature to 700 °C, a SmCo5phase and a SmCo7phase precipitate in sequence then the SmCo5transforms to SmCo7. The activation energies for the SmCo5and SmCo7crystallization are 2.5 ± 0.1 and 2.8 ± 0.1 eV, respectively. Differently, the SmCo/FeCo amorphous alloy processes only one phase transformation to SmCo7with an activation energy of 2.8 ± 0.1 eV after annealing to 700 °C. The present study gives an insight into the phase transformation of the SmCo amorphous alloys with different soft phase and is of basic significance to the microstructure controlling of the SmCo based nanocomposite magnets.
