The alloy subjected to optimum annealing treatment showed higher effective permeability and smaller magnetic core loss at 1 MHz than conventionally annealed alloy. The enhanced magnetic properties of the flash-annealed alloy were attributed to the reduced alpha-Fe phase grain size to 6 nm and the lower remanence ratio of about 0.3 in comparison to the conventionally annealed alloy with the values of 9 nm and 0.7, respectively. The results show that the flash annealing technique was effective in improving the high-frequency soft magnetic properties of Fe-B-Nb-Cu nanocrystalline alloy. (C) 1997 Elsevier Science S.A.
