Abstract
In an effort to obtain soft magnetic materials with excellent high-fre quency characteristics, effects of flash annealing on magnetic propert ies and microstructure in melt-spun Fe-B-Nb-Cu alloy with ultrathin ri bbon shape less than 10 mu m thickness were investigated. The alloy su bjected to optimum annealing treatment showed higher effective permeab ility and smaller magnetic core loss at 1 MHz than conventionally anne aled alloy. The enhanced magnetic properties of the flash-annealed all oy were attributed to the reduced alpha-Fe phase grain size to 6 nm an d the lower remanence ratio of about 0.3 in comparison to the conventi onally annealed alloy with the values of 9 nm and 0.7, respectively. T he results show that the flash annealing technique was effective in im proving the high-frequency soft magnetic properties of Fe-B-Nb-Cu nano crystalline alloy. (C) 1997 Elsevier Science S.A.
