本文研究了Ｆｅ７２．５Ｃｕ１Ｎｂ１．５Ｍｏ１．５Ｖ１Ｓｉ１３．５Ｂ９合金在不同热处理温度下磁性能的变化及其晶化过程。在ＦｅＣｕＮｂＳｉＢ合金中用Ｍｏ，Ｖ部分替代Ｎｂ仍能获得软磁性能良好的纳米微晶。其最合适的热处理退火条件为５３５℃，保温１小时。与用机械合金法合成纳米晶相比较，佐证了非晶晶化法形成纳米微晶，其优异的磁性能是由于微晶中同时存在晶粒和晶界两种磁相，晶粒与晶界之间有交换相互作用。
In this paper, the magnetic properties and the crystallization process of Fe72.5Cu1Nb1.5Mo1.5V1Si13.5B9 alloy at different heat treatment temperatures were studied. In the FeCuNbSiB alloy with Mo, V partially replace Nb still get good soft magnetic properties of nanocrystallites. The most suitable heat treatment annealing conditions for 535 ℃, incubated for 1 hour. Compared with the synthesis of nanocrystalline by mechanical alloying, the nanocrystallites formed by amorphous crystallization have been proved. The excellent magnetic properties are due to the existence of both magnetic and grain boundaries in the microcrystal. There is exchange of interaction between.
