FIM-ATOM PROBE INVESTIGATION OF MELT-SPUN PERMANENT MAGNETS BASED ON NdFeB
نویسندگان
چکیده
The microstructure of Nd15Fe7,B8 in the optimum magnetic state is compared to that of overquenched and heat treated specimens using Field Ion Microscopy (FIM) and Atom Probe (AP) techniques. Apart from the hard magnetic Nd2FeI4B ( (P ) and the nonmagnetic Nd,,,Fe4B4 ( 11 ) a metastable Nd7Fe3 phase controls the magnetic properties of melt-spun NdFeB ribbons. Furthermore the influence of a partial Fe substitution by CO on the microstructure was investigated and is presented in this report.

TEM INVESTIGATION OF RAPIDLY SOLIDIFIED NDFEB HARD MAGNETIC MATERIAL
The surface condition and microstructure of near stoichiometric (Fe823Ndll.8B5.9) Nd-Fe-B alloy ribbons and the effect of melt spinning parameters were investigated using optical, scanning and transmission electron microscopes (SEM, TEM). The formation of gas pockets on the roll surface of the ribbons during melt spinning can prevent heat transform and result in local coarse grains. The local t...
متن کاملThe Structure and Magnetic Properties of Co77Zr18W5 Melt-Spun Ribbons
Based on X-ray diffraction, microscopic and magnetic analysis, the structure and magnetic properties of Co77Zr18W5 melt-spun ribbons were studied in this paper. A new element to stabilize the metastable Co5Zr phase was found and the coercivity observed in Co-Zr alloys can be obviously enhanced by proper tungsten substitution. The Curie temperature of Co77Zr18W5 ribbons is 475 ̊C which suggests t...
متن کاملThe Pulse-Thermal Processing of ndFeB-Based nanocomposite Magnets
Pulse-thermal processing (PTP) based on high-density plasma arc lamp technology has been utilized to crystallize melt-spun NdFeB-based amorphous ribbons to form magnetic nanocomposites consisting of Nd 2 Fe 14 B and α-Fe phases. After applying suitable pulses, the NdFeB-based ribbons were developed with hard magnetic properties. The highest coercivity can be obtained for ribbons with a thicknes...
متن کاملDirectional annealing-induced texture in melt-spun (Sm12Co88)99Nb1 alloy
Developing texture in nanocrystalline permanent magnet alloys is of significant importance. Directional annealing is shown to produce texture in the permanent magnet alloy (Sm12Co88)99Nb1. Melt spinning produced isotropic grain structures of the hard magnetic metastable SmCo7 phase, with grain sizes of ∼300 nm. Conventional annealing of melt-spun (Sm12Co88)99Nb1 alloy produced Sm2Co17 phase wit...
متن کاملInfluences of Laser Spot Welding on Magnetic Property of a Sintered NdFeB Magnet
Laser welding has been considered as a promising method to join sintered NdFeB permanent magnets thanks to its high precision and productivity. However, the influences of laser welding on the magnetic property of NdFeB are still not clear. In the present paper, the effects of laser power on the remanence (Br) were experimentally investigated in laser spot welding of a NdFeB magnet (N48H). Resul...
