摘要：

In this work Al and Si are substituted for Fe in a (Fe,Si,Al)-Nb-B-Cu alloy with the goal of improving its magnetic properties at 77 K. The x-ray diffraction patterns for a series of five alloys annealed at 823 K shows a Fe(3)(Si,Al) ordered phase with some residual amorphous phase. The lowest coercivity at room temperature was observed for the alloy with composition Fe(68)Si(15.5)Al(3.5)Nb(3)B(9)Cu(1). At cryogenic temperatures, the saturation magnetization of 99.3 A m(2)/kg, coercivity of 0.45 A/m, and resistivity of 122 mu Omega cm for the Fe(63)Si(17.5)Al(6)Nb(3)B(9)Cu(1) alloy, compare favorably to commercial alloys at 77 K.
