摘要：
We have investigated influences of various elements (Ti, Nb, Mo, Ta, Hf, W, V, Cr) on magnetic properties of Fe-B/Nd2Fe14B-based Nd-Fe-B-Ti-C nanocomposite magnets in order to obtain larger coercivity required for high-temperature applications. As a result, addition of Cr was found to be most effective among additive elements investigated to enhance coercivity. Thermal flux losses of high-coercivity (H-cJ = 1609 kA/m) Nd-Fe-B-Ti-C-Cr nanocomposite magnet at 200 degrees C are less than 2%. (c) 2006 Elsevier B.V. All rights reserved.
