Abstract
Nanocrystalline Fe-Si-B-P-Cu alloys exhibit high saturation magnetic flux density (Bs) and extremely low magnetic core loss (W), simultaneously. Low amorphous-forming ability of these alloys hinders their application potential in power transformers and motors. Here we report a solution to this problem. Minor addition of C is found to be effective in increasing the amorphous-forming ability of Fe-Si-B-P-Cu alloys. It allows fabrication of 120Â mm wide ribbons (which was limited to less than 40Â mm) without noticeable degradation in magnetic properties. The nanocrystalline (Fe85.7Si0.5B9.5P3.5Cu0.8)99C1 ribbons exhibit low coercivity (Hc)~4.5Â A/m, high Bs~1.83Â T and low W~0.27Â W/kg (@ 1.5Â T and 50Â Hz). Success in fabrication of long (60-100Â m) and wide (~120Â mm) ribbons, which are made up of low cost elements is promising for mass production of energy efficient high power transformers and motors
