Investigation of rapidly quenched Nd-Fe-B alloys for production of high-coercivity composite magnets
The paper is devoted to producing and studying magnetic properties of rapidly quenched neodymium-iron-boron based alloys (RQA). Extreme dependence of coercive force upon quenching ratio and alloy chemical composition (neodymium and boron content) is shown. Particles produced by quenching are shown to be X-ray amorphous and isotropic. By means of thermal influence it is possible to improve the magnetic characteristics of RQA and powders on their basis. The optimal annealing temperature is 600...800/spl deg/C. Composite magnets, produced from the above RQA have the following properties: B/sub r/=0,53 T, /sub i/H/sub c/=1100 kA/m.
