Abstract
In order to enhance magnetic properties of hybrid Pr2(Fe,Co)14B/PrCo5 magnets, partial substitution of Fe for Co in the PrCo5 component was made. This substitution resulted in significant deterioration of intrinsic coercivity of PrCo5 and of the hot compacted hybrid Pr2 (Fe,Co)14B/PrCo5. However, after hot deformation, the intrinsic coercivity of hybrid Pr2(Fe,Co) 14B/Pr(Co1-xFex)5 increased with increasing Fe content in the Pr(Co1-xFex)5 component up to x=0.3. The SEM/EDS analysis revealed the formation of a Pr-rich Pr2(Co0.64Fe0.36)7 phase at the interface of Pr2(Fe,Co)14B and Pr(Co,Fe)5 . However, the mechanism of the coercivity enhancement is yet to be elucidated
