Abstract

New ferromagnetic Fe-based (Fe, Co, Ni)67.5Mo7.5P10C10B5 bulk metallic glasses have been developed based on an Fe75P10C10B5 alloy. These alloys exhibit large supercooled liquid region of 97-102 K, low glass transition temperature of 727-738 K, high glass-forming ability (GFA) with critical sample diameters of 3-4 mm, and low viscosity values on the order of 107 Pa s in the supercooled liquid state. The magnetic and mechanical measurements reveal that the alloys also possess good soft magnetic and mechanical properties, i.e., low coercive force of 3.04-4.37 A/m, rather high saturation magnetization of 0.77-0.83 T, high yield strength of 3344-3463 MPa, and large plastic strain of 0.6-1.1%. In addition, the effects of Mo, Co and Ni addition on the stabilization of supercooled liquid and GFA in the Fe-P-C-B alloy system have been discussed.
