摘要
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。
The variation of magnetic properties and crystallization behavior of Fe 72 5 Cu 1Nb 1 5 Mo 1 5 V 1Si 13 5 B 9 alloy with heat treatment at different temperatures is investigated. Nanocrystalline alloy with excellent soft nagnetic properties can be obtianed by the substitution of Mo and V elements for part of Nb in Fe Cu Nb Si B alloy. The optimum annealing condition is about 535℃ for one hour. The comparison with the nanocrystalline alloys prepared by the ball milling method suggests that the excellent magnetic properties of the nanocrystalline alloys prepared by the crystallization of amorphous alloys can be attributed to existence of both crystalline grain and crystal boundary in the nanocrystalline alloy, between which there is an exchange interaction.
