【摘要】 本文系统研究了Fe_100-xZr_x,(Fe_1-xZr_x)84B₁₄和Fe_90-xMxZr₁₀（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。更多还原

【Abstract】 The composition dependence of the crystallization temperature Tcr for Fe100-xZrx, j(Fe1-x Zrs,)84B10, and Fe90_x MxZr10(M = V,Cr,Mn,Co,Ni,Si,B) amorphous alloys is investigated systematically. The main results are: the substitution of Zrfor some Fe in Fe-based amorphous alloysTcr exhibits an increase markedly; for amorphous Fc90-xMiZr10 alloys, Tcr increases following the order M = Mn, Cr, V and with increasing M content x, and decreases following the order M = Co, Ni and with increasing x; in most of the samples studied, the ratio of crystallization temperature to melting point is about 2/3; when the alloy composition was varied ( <20at%-M) or an alloying transition element was added, Tcr increased linearly with decreasing average number outer electrons per atom which was calculaied by taking into account both the s,p and d electrons of the transition metal atoms. These results are discussed in connection with various factors such as composition, phase diagram, melting point, interatomic force and e/a effecting the stability of amorphous alloys.更多还原
