Abstract

The magnetic properties of cast and hot- rolled Pr17Fe77.5 B4M1.5 (M=Cu, Ga, Ag, Al, In and Pb) alloys were investigated, in order to explore the rule of additive elements in improving the magnetic properties in the Pr-Fe-B system. It is found that Ga and Ag additions have a similiar effect as Cu in increasing the coercivity in both cast and hot-rolled specimens. The coercivity of these hot-rolled magnets containing Ga, Ag or Cu can easily reach 10k0e or greater. This is due to the grain refinement as well as the enhanced smoothing of grain boundaries.
