Effect of spark plasma sintering on the interphase exchange coupling in SmCo5+20%Fe hard/soft nanocomposites

Résumé

The hard/soft SmCo5+20wt% α-Fe exchange coupled nanocomposite powders are obtained by mechanical milling of SmCo5 and α-Fe powders. The compact densities range between 35% and 70% of the theoretical value. The sintered compacts show the same coercivity as the nanocomposite powders, 0.8 T, while the remanence and energy product were diminished. The plasma sintered nanocomposite SPS compacts are found to contain two hard magnetic phases: SmCo5 and Sm2(Co0.8Fe0.2)17, the latter being detrimental to the coercivity of the hard/soft nanocomposite
