Wf. Miao et al., EFFECT OF MECHANICAL MILLING ON THE STRUCTURE AND MAGNETIC-PROPERTIESOF ND16FE76B8, Journal of physics. D, Applied physics, 29(9), 1996, pp. 2370-2375
The effect of mechanical milling on the structure and magnetic propert
ies of Nd16Fe76B8 has been studied. Decomposition during milling was f
ound to occur via a two-stage reaction involving partial disordering a
nd amorphization of the Md2Fe14B phase, followed by the formation of a
lpha-Fe. Magnetic behaviour was found to depend on the microstructure
developed during milling. Exchange spring behaviour was observed in pa
rtially amorphized samples. The influence of annealing on the structur
e and magnetic properties of milled powders was also investigated.
