Magnetic Properties and Structure of Nanocrystalline Nd_(4.5)Fe_(76)Co_1B_(18.5) Alloys

In this paper, the technology, structures and magnetic properties of Nd4.5Fe76Co1B18.5 nanocomposite magnets were investigated. The effect of crystallizing treatment temperature and time on structures and magnetic properties of Nd4.5Fe76Co1B18.5 amorphous ribbons was studied. The results show that Nd4.5Fe76Co1B18.5 containing more analogue metals is easy to form a morphous. The magnetic properties of 16 m/s quenched ribbon for 710 degrees Cx900 s crystallizing treatment reach H-i(c)=242.1 kA/m, B-r=0.9410 T and (BH)(max)=59.64 kJ/m(3). The even grain size is about D-Fe3B=34 nm and D-Nd2Fe14B=23 nm.
