  • Abstract
    A series of isotropic nanocomposite permanent magnets composed of Nd2Fe14B (the majority phase) and Fe3B and/or Fe23B6 are developed by converting phase formation behavior with partial replacement of Fe with Ti and B with C. The glass forming ability of the melt of the new series of alloys is great enough to allow application of the strip casting technique as the means of rapid solidification process. Powders exhibit excellent magnetic properties ranging from (Br,HcJ)=(0.88 T, 470 kA/m) to (0.80 T, 1010 kA/m), closely matching to the property range covered by the conventional isotropic Nd-Fe-B hard magnetic powders.
