説明
<jats:p>Amorphous melt-spun ribbons of Pr8Fe86–xTixB6 (x = 0–10) alloys were successfully consolidated into bulk materials by the spark plasma sintering method. X-ray diffraction and transmission electron microscopic studies revealed that the resultant bulk materials consisted of nanosized grains of the α-Fe and Pr2Fe14B phases. The coercivity of the Pr-Fe-Ti-B bulk nanocomposite magnets increased with increasing Ti content. The Pr8Fe80Ti6B6 bulk nanocomposite magnet exhibited a high remanence of 10.2 kG with a coercivity of 4.9 kOe, while the Pr8Fe76Ti10B6 bulk magnet exhibited a remanence of 6.5 kG with a high coercivity of 8.2 kOe.</jats:p>
