高能球磨处理非晶合金Fe_(78)Si_9B_(13)的晶化特点

Crystallization Characteristics of Amorphous Alloy Fe 78 Si 9B 13 Treated by High Energy Milling

对非晶合金进行了高能振动球磨处理，用穆斯堡尔谱学结合Ｘ光衍射等技术研究了球磨后试样的晶化结构．结果表明，经一定时间球磨，试样发生了晶化，析出基体金属相αＦｅ（Ｓｉ），但其对应的超精细磁场值相对较低．

The crystallization structure of speciments after milling was studied by Mssbauer spectroscopy and X ray diffraction. It is found that the amorphous speciments can be crystallized by ball milling in a given time. But the value of hyperfine magnetic field for the base metal phase α Fe(Si) precipitated from amorphous precursor is lower than that by other methods.
