摘要: Mechanical alloying is applied to prepare Nd‐Fe‐B, Sm‐Fe‐TM type (TM: V, Ti, Zr), and interstitial nitride carbide permanent magnets. Starting from elemental powders, the hard magnetic phases are formed by milling in a planetary ball mill following solid‐state reaction at relatively low temperatures. For magnetically isotropic particles microcrystalline, show high coercivity (up 16 kA/cm for ternary alloys above Dy‐substituted samples), can be either used making bonded magnets or compacted dense hot uniaxial pressing. Magnetically anisotropic samples with remanence up 1.31 T an energy product 326 kJ/m3 die upsetting. The mechanical process has also been material of three new phases: Sm‐Fe‐V ThMn12 structure, Sm‐Fe‐Zr PuNi3 Sm‐Fe‐Ti A2 structure. They all ultrahigh coercivities 51.6 Sm‐Fe‐Ti...
