利用低能核物理技术,通过磁参量和电阻的测量以及利用DSC方法,研究了非晶合金(Fe_(0.1)Ni_(0.35)Co_(0.55))_(78)Si_8B_(14)的结构弛豫和转变。结果表明,在50—500℃范围内,结构弛豫和转变可分为四个阶段。在175—200℃和400—420℃区域内产生两种不同特征的结构弛豫,对应着磁性的不同变化。结构弛豫中发展了化学短程序和拓扑短程序,产生感生磁各向异性。考查了低温结构弛豫和高温转变的动力学行为。用结构缺陷模型讨论了结构弛豫中结构缺陷的变化。
The structural relaxation of Fe_ (0.1) Ni_ (0.35) Co_ (0.55)) _ (78) Si_8B_ (14) amorphous alloy by low energy nuclear physics, magnetic parameter and resistance measurement and DSC method were studied. change. The results show that in the range of 50-500 ℃, the structure relaxation and transformation can be divided into four stages. Structural relaxation of two different characteristics occurs in the 175-200 ° C and 400-420 ° C regions, corresponding to different magnetic changes. Structural relaxation in the development of short chemical short program and topology, resulting in induced magnetic anisotropy. The dynamic behavior of low temperature structure relaxation and high temperature transformation was investigated. Structural defect model is used to discuss structural defects in structural relaxation.
