摘要：
Thermal behavior and microstructure of Fe(81-x)Co(x)Zr(7)Nb(2)B(10) (x = 2, 4, 6) alloys were investigated by differential thermal analysis and X-ray diffraction. Both the supercooled liguid region Delta T(x) and the first crystallization peak temperature To are the lowest and the span Delta T(p) between To and T(p2) is the highest when 4 at.% Fe is substituted by Co. The crystallization activation energy E(p1), for Fe(75)Co(6)Zr(7)Nb(2)B(10) alloy is the minimum for the heating rates v = 5-20 K/min. E(p1) for Fe(77)Ca(4)Zr(7)Nb(2)B(10) alloy is the minimum for the heating rates v = 20-50 K/min. The crystallization processes of Fe(81-x)Co(x)Zr(7)Nb(2)B(10) (x = 2, 4, 6) amorphous alloys are similar on the whole, which is as follows: amorphous amorphous + alpha-Fe(Co) alpha-Fe(Co) + Fe(3)Zr + Fe(2)Nb(0.4)Zr(0.6).
