Abstract

The effect of Cr addition on the glass-forming ability (GFA), the magnetic properties, and corrosion resistance of (Fe0.76Si0.096- B0.096P0.048)100-xCrx (x = 0, 2, 4 and 6) bulk glassy alloys (BGAs) with high Fe contents was investigated. 4% Cr addition makes the alloy composition to approach towards a eutectic point, which could result in an increase in the GFA. The BGA rod with diameters up to 3 mm was produced by copper mold casting. These BGAs exhibit a rather high saturation magnetization of 1.10-1.50 T and lower coercive force of 1.4-2.4 A/m. A significant improvement in corrosion resistance was observed with increasing Cr content. Furthermore, these Fe-based BGAs exhibit super high strength of ∼3.3 GPa and Young's modulus of 168 GPa.
