摘要：

The effect of variable cobalt concentration and variable annealing times on the hard magnetic properties of Nd-Fe-C-type ingot magnets was studied. It was found that cobalt substitution can lead to a significant decrease in the annealing time needed to harden the ingots magnetically. A simple production route is described in which an isotropic ingot magnet is obtained after annealing for several hours with (BH)max = 70 kJ m-3, B(r) = 0.63 T and (J)H(c) = 900 kA m-1.
