摘要
研究了F360系列的电磁式漏电断路器中FeSiCuNbB纳米晶软磁磁芯的非晶晶化过程。研究发现,快淬薄带淬态组织以非晶相为主,含有少量α-Fe(Si)晶化相;合金非晶晶化过程存在两个阶段,分别对应于α-Fe(Si)相和Fe2B相析出,其晶化激活能分别为291.16 kJ/mol和430.88 kJ/mol;磁芯经过510℃晶化处理后,获得最佳综合磁性能,满足了电磁式漏电断路器的要求。
Crystallization of FeSiCuNbB nanocomposite soft magnets used in F360 leakage breaker is studied in this paper.The as-spun ribbons are composed of amorphous phase and few αFe(Si) phase.The crystallization of amorphous ribbons takes place by two steps,corresponding to the precipitation of αFe(Si) and Fe2B phase with crystallization activation energy of 291.16 kJ·mol-1 and 430.88 kJ·mol-1,respectively.The magnetic core annealed at 510 ℃ shows the optimum soft magnetic properties that are suitable for F360 leak...
