Partitioning behavior and the effect of Co on the Curie temperature of nanocomposite PrFeCoB hard magnetic alloys

Abstract:

The microstructure and phase chemistry of melt-spun nanocomposite Pr9.7Fe76.6Co7.8B5.9 and Pr9.2Fe69.4Co15.4B6.0 ribbons have been studied using three-dimensional atom probe (3DAP) and transmission electron microscopy. The microstructure of these alloys consists of two phases, bcc α-Fe-Co and tetragonal Pr2(FeCo)14B. Practically all of the B and Pr atoms are rejected from the α-Fe-Co phase and are concentrated into the 2/14/1 hard magnetic phase. However, no significant difference of Co conce...
