N2 - The effects of alloying elements on the thermal stability, glass-forming ability (GFA), corrosion resistance, and magnetic and mechanical properties of a soft magnetic Fe75P10C10B5 metallic glass with a low glass transition temperature (T g) of 723 K (450°C) were investigated. The addition of Mo, Ni, and Co significantly increased the stabilization of supercooled liquid, GFA, and corrosion resistance in the H2SO4 solution. The maximum critical diameter (d c) of 4 mm for glass formation was obtained for the Fe 55Co10Ni5Mo5P10C 10B5 alloy, which shows the largest supercooled liquid region (ΔT x ) of 89 K (89 °C). The substitution of Cr for Mo further enhanced the corrosion resistance of the Fe55Co 10Ni5Mo5P10C10B 5, while the ΔT x and d c decreased. The (Fe, Ni, Co)70(Mo, Cr)5P10C10B 5 bulk metallic glasses showed low T g of 711 K to 735 K (438 °C to 462 °C), wide ΔT x of 67 K to 89 K, high saturation magnetization of 0.79 to 0.93 T, low coercive force of 2.36 to 6.61 A m-1, high compressive yield strength of 3271 to 3370 MPa, and plastic strain of 0.8 to 2.3 pct. In addition, the mechanism for enhancing stability of supercooled liquid was discussed in terms of the precipitated phases during crystallization.
