Abstract

The effect of selected refractory metals addition on the structure and magnetic properties was studied for the nanocomposite Nd9Fe77−xB14Mx (M  =  Ti, Mo, Nb, Mn), Nd8Fe78−xB14Mx (M  =  Ti, Mo, Nb, Mn) and Nd7Fe79−xB14Tix systems. It was found that the addition of 2 and 4 at \% of refractory metals leads to a substantial increase of the coercivity and maximum energy product for each of the nanocomposite systems while maintaining the remanence unchanged. The highest properties were obtained for the alloys containing 4–5 at\% of the refractory metals. The maximum energy product of 143 kJ/m3 was achieved for the Nd8Fe74B14Ti4 alloy.
