Abstract
We optimized the alloy compositions by modifying the Nb content in [(Fe0.5 Co0.5) 0.75 B0.20 Si0.05] 100-x Nbx (x=3.6-4.4) alloy system. As a result, it was found that the Nb content of 4.3 at. % was effective for approaching alloy to a eutectic point. By copper mold casting, [(Fe0.5 Co0.5) 0.75 B0.20 Si0.05] 95.7 Nb4.3 bulk glassy alloy rods with diameters up to 4 mm were successfully synthesized even using commercial raw materials. These glassy alloys exhibit a rather high saturation magnetization of 0.77 T and low coercive force of 2.5 A/m.
