Materials Research Science and Engineering Center: Faculty Publications

Permanent magnets with the general composition Pr₉ (Fe_0.95Co_0.05)_85.5M_0.5B₅, where M denotes a transition metal, have been produced by melt spinning. The effect on the microstructure and magnetic properties of eight different alloying elements has been examined. The grain size and distribution have been correlated to the maximum energy product obtained. The grain size of the Pr₉ (Fe_0.95Co_0.05) _85.5B₅ control alloy was determined to be 17.5 nm, and it was found that the grain size was not significantly reduced compared to the control …
