Fe75-xCoxCu1Nb3Si15B6 Alloy with Rapid Stress Annealing

This Articler reports the effect of stress annealing treatment on the structural and magnetic properties of nanocrystalline Fe75-xCoxCu1Nb3Si15B6 & Co21Fe64-xNbxB15 alloys. Information obtained from magnetic measurements, X-ray diffraction measurements and Mössbauer spectroscopy reveal that for Fe75-xCoxCu1Nb3Si15B6 (x = 0, 2, 5) alloys the volume fraction of the Fe-Co nanograins and their grain diameter ranges between 56 to 80 % and 10 to 18 nm respectively. Annealing treatment at higher temperature also resulted in appearance of Fe3Si nanocrystals along with magnetically hard Fe3B, Fe23B type phases which are responsible for higher coercive field values. Presence of cobalt and applied stress during annealing has considerable effect on relative permeability and stress induced anisotropy, which is and perpendicular to the ribbon axis. Mössbauer spectroscopy analysis also suggests changes in spin texture.
