本文系统研究了Fe_(100-x)Zr_x,(Fe_(1-x)Zr_x)84B_(14)和Fe_(90-x)MxZr_(10)(M=V,Cr,Mn,Co,Ni,Si,B)非晶态合金的晶化温度与成分的关系。主要结果有:用Zr替代Fe使晶化温度明显提高;在FeMZr非晶态合金系列中,晶化温度依M=Mn,Cr,V元素的顺序和M含量x的增大而提高,而依M=Co,Ni元素的顺序和x的增加而下降;大多数样品的晶化温度与其熔点的比值约为2/3;晶化温度随过渡金属元素的每个原子平均外层电子浓度e/a的减少近似线性地增加(M元素含量<20at%)。对这些实验规律,从组份、相图、熔点、原子间的结合作用、e/a等进行了讨论。
In this paper, the effects of Fe_ (100-x) Zr_x, Fe_ (1-x) Zr_x) 84B_ (14) and Fe_ (90_x) MxZr_ (10) , B) amorphous alloy crystallization temperature and composition. The main results are as follows: the substitution of Zr for Zr increases the crystallization temperature significantly; in the FeMZr amorphous alloy series, the crystallization temperature increases with the increase of M, Mn, Cr, V elements and M content, M = Co, the order of Ni elements and the decrease of x; the crystallization temperature of most samples is about 2/3 of its melting point; the crystallization temperature varies with the average outer electron concentration of each atom of transition metal elements e / The decrease in a increases approximately linearly (M element content <20 at%). The rules of these experiments, from the composition, phase diagram, melting point, the binding between atoms, e / a and so on are discussed.
