| 摘 要： | 测试了制备态非晶(Fe1-xNix)76Si8B16合金在较低温度(65—150℃)下等温时效过程中磁导率的变化。结果表明:在65℃以下时效,磁导率变化不大;在100℃以上时效,磁导率发生了明显变化,此变化与合金成分有关。用应力、磁致伸缩和感生磁各向异性的变化对实验结果进行了圆满的解释。

| Abstract: | Changes of permeability have been measured for as-received amorphous (Fe1-xNix)76Si8B16 alloys after aging for different times at relative low temperatures (65-150℃). The results indicate that the permeability is almost unchanged after aging below 65℃ but it varies obviously above 100℃. The changes of permeability are dependent on the alloy compositions and can be interpreted in terms of the changes of stress, magnetostriction and induced magnetic anisotropy during aging. |
