Formation of Structure and Magnetic Properties in Permanent Magnets Obtained by Pressing and Sintering of Micropowders of Alloy Fe2NiAl with Fusible Additions

  • Published:
Metal Science and Heat Treatment Aims and scope

Results of a study of magnetic properties and structure of specimens of magnets obtained from heat-treated cast alloy Fe2NiAl milled in a planetary mill together with CuAl2 and Al addition alloys, pressed in a magnetic field, and sintered in vacuum or by spark plasma sintering (SPS) are presented. The suggested method for fabrication of sintered permanent magnets gives solid hard magnetic materials with high coercivity and relatively high saturation magnetization.
