The new generation of FeNbCuSiB based alloys were prepared in the form of ribbons by rapid quenching route using melt spinning technique.Differential scanning calorimetry (DSC) and thermal electrical resistivity (TER) measurements indicated the generation of nanophase from the ascast amorphous state. The ribbons prepared at optimum quenching wheel velocity of 32m/s exhibited low brittleness with sup-erior soft magnetic properties in the as-cast state. The superior quality ribbon sample indicated ultrasoft magnetic properties at an annealing temperature of 790K. This was due to the generation of nanoparticles as evid-enced from the transmission electron microscopy (TEM). Potentiodynamic polarization studies showed that the material exhibited good corrosion resistive properties around optimum annealing temperature of 790K.
