| 摘 要： | 本文系统研究了(Fe1-xMx)84B16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Tcr约为1/2,在0.42—0.62之间,符合Sakka规则。Fe1-x-yBxSiy的Tcr>Fe1-xBx>Fe1-x-yBxPy。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。

| Abstract: | In this paper, the relationship between composition and crystallization temperature of Fe-base amorphous alloys are investigated systematically. Among 95 Fe-base amorphous alloys, the crystallization temperatures of about 85% of them are in the range of 700-825 K, Tcr/Tm≈1/2 (0.42-0.62), and conform to Sakka's principle The crystallization temperature of Fe1-x Bx-ySiy is greater than that of Fe1-xBx and the later greater than that of Fe1-xBx-yPy in turn. Those mentioned above are discussed with reference to the composition, phase diagrams, machanism of the crystallization, diffusion and the relationship between the crystallization temperature and the average electronic concentration (e/a). |
