1.STUDY OF M?SSBAUER EFFECT, FERROMAGNETIC RESONANCE AND COERCIVE FORCE OF COLUMNAR CRYSTALLINE Fe-Cr-Co-Mo-Ti AND ALNICO 5 PERMANENT MAGNET
2.The relationship between the depth of carburized layer and magnetic coercive force was studied. Based on this relationship we measured the depth of carburized layer by electromagnetic nondestructive measurement instrument (DWY-1).
3.At the plating condition of bath load 3g/L and plating temperature 80 degree Celsius, the density of powder was of 0.98g/cm~3. The coercive force, saturation induction density and retentive magnetism for the coated cenospheres were 39789A/m, 43A·m~2/kg and 12A·m~2/kg respectively.
4.(3) under the sintering conditions of P=5.5 GPa, t=3 min, when Pw≥980 W, single phase α-Fe nanocrystalline (20.3 nm) bulk alloy with over 98.2% relative density can be obtained, soft magnetic properties of the bulk alloy are: specific saturation magnetization Ms=154.0 emu·g-1, coercive force Hc=7.474×103 A·m-1.
5.The effect rules of alloy structure, phase components, phase evolvement during the HDDR process and the surface condition of the magnetic powder after milling on the intrinsic coercivity was searched by means of XRD,SEM,AFM. It was found that the metastable phase of Sm10Fe90 in TbCu7 type decreased the content of N in Sm2Fe17Nx at the recombination temperature of less than 800℃, which can decreased the coercive force of Sm2Fe17 Nx magnetic material.
6.The presence of a small amount of CaO in the zine -bearing square-loop mangane- se-magnesium ferrites tends to change their static magnetic properties so that the re- ctangular ratio(Br/Bm)is increased from 0.88 to 0.93 and the coercive force (Hc)is reduced from 0.63 oersted to 0.43 oersted. Thus these CaO-admixed ferrites better meet the specific requirments as square-loop magnetic materials.
