Crystallization behavior of melt-spun Nd{sub x}Fe{sub 93{minus}x}Nb{sub 1}B{sub 6} alloys
- Univ. of Delaware, Newark, DE (United States). Dept. of Physics and Astronomy
The crystallization behavior of Nd{sub x}Fe{sub 93{minus}x}Nb{sub 1}B{sub 6} melt-spun ribbons was investigated using calorimetric techniques. The crystallization products were identified by X-ray diffraction and thermomagnetic measurements. Samples with x {ge} 10 crystallization directly from amorphous to a mixture of Nd{sub 2}Fe{sub 14}B and {alpha}-Fe phases. For 10 < x < 7, the final mixture of 2:14:1 and {alpha}-Fe phases. For 10 < x < 7, the final mixture of 2:14:1 and {alpha}-Fe phases is obtained through a two stage crystallization where the intermediate metastable Nd{sub 2}Fe{sub 23}B{sub 3} and Nd{sub 3}Fe{sub 62}B{sub 14} phases are produced at the initial crystallization. In samples with 7 < x < 4 the intermediate phase is Nd{sub 3}Fe{sub 62}B{sub 14}. No metastable phases were observed in samples containing less than 3 at. % Nd although the calorimetric measurements indicated a two-step crystallization process.
