Abstract

The effect of Nb micro-addition on the glass-forming ability, magnetic and corrosion properties of (Fe 0.76Si 0.09B 0.1P 0.05) 100-xNb x (x = 0-4) alloy system was investigated. It was found that micro-addition of 1% Nb is effective in increasing the critical diameter for glass formation from 2.5 for the base alloy to 3.5 mm for (Fe 0.76Si 0.09B 0.1P 0.05) 99Nb 1 glassy alloy. Moreover, the 1% Nb-containing glassy alloy exhibits excellent soft-magnetic properties, i.e., high saturation magnetization (I s) of 1.45 T and low coercive force (H c) of 1 A/m. A significant improvement in corrosion resistance of the glassy alloys with Nb micro-alloying in 1 N H 2SO 4 solution is also observed. The good combination of high glass-forming ability (GFA), excellent soft-magnetic properties and enhanced corrosion resistance indicates the possibility of future development as new engineering and functional materials.
