Description

In this study, novel Fe based nanocrystalline Fe82Nb6B9P3 alloy was developed. The microstructure and magnetic properties were investigated. Precursor Fe82Nb6B9P3 amorphous alloy ribbon was prepared by using planar-flow melt-spinning method. Fine grain structure with higher density dispersion of bcc-Fe crystal was observed after heat treatment for crystallization with Fe82Nb6B9P3 alloy. Fe82Nb6B9P3 alloy with nanocrystalline structure exhibited high magnetic flux density ( Bs ) of 1.64T at room temperature and low core loss( Pcv ) of 650kW/m3 at 100kHz and 200mT compared with conventional nonequilibrium type Fe based soft magnetic materials. The newly developed Fe82Nb6B9P3 alloy with excellent magnetic softness is suitable for improving the performance of high-density power supplies using magnetic components. (author)
