Synthesis and properties of ferromagnetic Fe-based (Fe, Ni, Co)–Mo–P–C–B bulk metallic glasses with large supercooled liquid region
چکیده انگلیسی

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.
