HITPERM 型软磁合金Fe(Co)-M-B-Cu(M=Nb、Zr、Hf 等)由于结构的特殊性使得其具有优异的高温软磁性能,最有希望用于第二代电
动航天飞机(MEA)和其它高温应用领域,是目前软磁材料开发的热点之一.本文采用正电子湮没寿命谱的实验手段,对淬态非晶合金(Fe1-xCox)86Hf7B6Cu1 (x=0.0.5)中频磁脉冲处理前后的结构缺陷进行了研究.
\x05正电子湮没技术是通过入射正电子与材料中电子结合湮没而反应材料中微结构状态与缺陷信息的.正电子湮没寿命谱采用快——快符合 ORTEC 系统进行测量,将所测得的寿命谱分解为3个指数衰减成分进行拟合解谱,得到正电湮没寿命i以及与之对应的湮没强度Ii(i=1、2、3).其中1对应于单空位(或类单空位)中的正电子湮没,2对应于空位团中的正电子湮没,3主要归因于源表面、样品内表面或者源与样品之间的空隙等处正电子湮没.研究表明,经中频磁脉冲处理后,(Fe1-xCox)86Hf7B6Cu1 (x=0.0.5)合金的正电子湮没寿命值i总体上均呈现出下降的趋势,各寿命成分所对应的强度Ii亦发生较小幅度的波动.这意味着经中频磁脉冲处理后,非晶合金要发生微结构及结构缺陷的变化,导致试样的正电子湮没参数亦要伴随着改变.另外,淬态非晶合金中Co含量(x)的变化对(Fe1-xCox)86Hf7B6Cu1 (x=0.0.5)非晶合金中正电子湮没寿命是有影响的.其中,x=0.4成分的样品对应的第一寿命值(1)与第二寿命值(2)均较小,说明x=0.4成分的样品中所含类单空位与空位团体积均较小.
