Abstract
Hard magnetic properties have been found in homogenized and subsequently aged Pr–Zr–Co alloys. Transmission electron microscopy reveals a microstructure consisting of a Pr2(Co, Zr)17 matrix with (Pr, Zr)Co5 precipitates formed after aging the homogenized alloys with the (Pr, Zr)Co5+δ structure. This microstructure is similar to that of the Sm–Co–Cu–Zr precipitation-hardened magnets. However, unlike Sm2Co17, the easy magnetization direction (EMD) of Pr2Co17 lies in a basal plane. The coexistence of the 2:17 matrix phase with EMD∥(001) and the 1:5 cell-boundary phase with EMD∥[001] results in unusual alignment effects. Anisotropic Pr11.5Zr4Co85 powders with coercivity of 4.1 kOe and energy product of 7.2 MGOe were obtained.
