本文系统研究了(Fe(1-x)M_x)_(84)B(16)系非晶合金(x=0.02—0.20;M=Ti,Zr,V,Nb,Ta,Cr,Mo,W,Mn,Co,Ni)的晶化温度与组成的关系。晶化温度随M=VIIB,VIB,VB,IVB元素的顺序和x值的增大而提高。M=VIII族(CO,Ni)元素时,晶化温度基本相同,并随x值的增大略有降低。对于被研究的95个Fe基非晶合金,晶化温度在700—825K的约占85％,熔点Tm/晶化温度T_(cr)约为1/2,在0.42—0.62之间,符合Sakka规则。Fe(1-x-y)B_xSi_y的T_(cr)>Fe_(1-x)B_x>Fe_(1-x-y)B_xP_y。对上述规律性,从组份、扩散、相图以及晶化温度与合金元素外层平均电子浓度/α的关系进行了讨论。
In this paper, we systematically studied the effects of Fe (1-x) M_x) _ (84) B (16) -based amorphous alloys (x = 0.02-0.20; M = Ti, Zr, V, Nb, Ta, Cr, Mo, Mn, Co, Ni) crystallization temperature and composition of the relationship. The crystallization temperature increases with the order of M = VIIB, VIB, VB, IVB elements and the increase of x. When M = Group VIII (CO, Ni) element, the crystallization temperature is basically the same and decreases slightly with the increase of x value. For the 95 Fe-based amorphous alloys studied, the crystallization temperature is about 85% at 700-825K, the melting point Tm / crystallization temperature T_cr is about 1/2, and between 0.42-0.62, in line with Sakka rule. T_ (cr)> Fe_ (1-x) B_x> Fe_ (1-x-y) B_xP_y of Fe (1-x-y) B_xSi_y. The above regularity is discussed in terms of composition, diffusion, phase diagram, and the relationship between the crystallization temperature and the average electron concentration of the outer layer of the alloying element / α.
