摘要
用激波冲击 (Fe0 99M0 0 1 ) 78Si9B1 3非晶软磁合金 ,非晶相发生相变 ,形成纳米尺寸的α (Si,Mo)主晶相和第二相 ,电子衍射详细研究了第二相。用Fe2 B等的粉末衍射数据卡数据来标定第二相的单晶电子衍射谱偏离大。通过对实验数据的大量计算 :第二相被确认为Si固溶于Fe2 B的 (Fe,Si) 2 B ,其点阵常数与Fe2 B有一定差别 ,为a =0 4 895 0nm ,c=0 880 2 3nm ,Si的溶质成分估计为 10 7%。
After (Fe 0 99 Mo 0 01 ) 78 Si 9B 13 amorphous soft magnetic alloy was blasted by shock wave,amorphous phases were transited into α Fe(Si,Mo) primary crystalline phase and secondary phase in nanometer size. Secondary phase was minutely studied by means of electron diffraction(ED). Single crystal ED pattern of the phases was indexed by powder diffraction file(PDF)data of substance Fe 2B et al.,so that the result has large deviation. Through a great deal of computation of experimental data,secondary phase was confirmed as (Fe, Si) 2B, where Si as solute atom substitute dissolved in Fe 2B. Its lattice constants are a = 0 48950nm, c = 0 88023nm.This is different from Fe 2B, Si solute composition was estimated at 10 7%.
