%X In this article, the quenched Nd4.5Fe75Co1Si1B18.5 ribbons were prepared, and the structures and properties were investigated. The results show that the change of structures of Nd4.5Fe75Co1Si1B18.5 quenched amorphous ribbons is Am-->Am' +Fe3B+ Nd2Fe23B3+ Nd2Fe14B-->Fe-3 B+Nd2Fe14B when it is heated. The effect of crystallizing treatment temperature and time on the magnetic properties of the quenched alloy was studied. The magnetic properties of 16 m/s quenched ribbons for 710 degrees Cx1200 s crystallizing treatment reach H-i(c)=238.6 kA/m, B-r=0.8987 T and (BH)(max)=51.39 kJ/m(3). The grain size is about D-Fe3B=32 nm and D-Nd2Fe14B=22 nm.
