摘要
An Fe-base nanocrystal soft magnetic alloy of low megnetostriction and high saturation magnetic flux density having properties especially appropriate for cut cores; an amorphous alloy ribbon for use in production of the Fe-base nanocrystal soft magnetic alloy; a process for producing the Fe-base nanocrystal soft magnetic alloy; and high-performance magnetic parts utilizing the alloy. The Fe-base nanocrystal soft magnetic alloy has the composition of the general formula Fe100-x-a-y-zAxMaSiyBz (in the formula, A is at least one element selected from among Cu and Au; M is at least one element selected from among Ti, V, Zr, Nb, Mo, Hf, Ta and W; and x, a, y and z each represent atomic% and satisfy the relationships 0≤x≤2, 0≤a≤1.5, 12≤y≤18, 4≤z≤10 and x+a+y+z≤25). The Fe-base nanocrystal soft magnetic alloy consists of bccFe-Si crystal grains of 120 nm or less average grain diameter and an amorphous phase, wherein the bccFe-Si crystal grains occupy, by volume, 50% or more of the structure. The Fe-base nanocrystal soft magnetic alloy has a saturation magnetic flux density (Bs) of 1.4 T or greater and a saturation megnetostriction constant (λs) satisfying the relationship -3.5×10-6≤λs≤+3.5×10-6.
