Abstract
Melt-spun Fe83B9Nb7Cu1 alloy viith ultrathin ribbon has been studied with Mossbauer spectroscopy and X-ray diffraction. The enhanced magnetic property of the flash-annealed alloy was attributed to the reduced alpha-Fe phase grain size to 6, nm and the higher effective permeability and smaller magnetic core loss at I MHz than conventional annealed alloys, The occupied area of the nanocrystalline phase at the optimum 773 K is about 73% whereas that for conventional annealing temperature at 893 K is about 71%, The flash annealing technique was effective in improving the high-frequency soft magnetic property of nanocrystalline Fe83B9Nb7Cu1 alloy.
