Fe-Cu合金的组织、力学性能和电磁性能
摘要
【摘要】 针对当前电机普遍存在的能源浪费问题进行导磁导电材料的研究
采用感应加热炉熔炼炉制备Fe-Cu合金
对合金进行正火、淬火+回火处理
通过金相显微镜、扫描电镜等对其微观组织观察研究
并测试其硬度、冲击韧性等力学性能和电磁性能.结果表明
Fe-Cu合金的基体为铁素体
Cu主要分布在奥氏体晶界处.热处理后合金的硬度和冲击韧性发生了变化
随着Cu质量分数的增加
磁导率和电阻率降低
Fe-20%Cu合金的组织均匀
电阻率、起动转矩比常用电机材料铸铝大
满足电机对导磁导电材料的使用要求.
Abstract
Regarding to the common energy wastage problem of motor
the research on the magnetic and elec-tric conductive material has been operated.Several Fe-Cu alloys with different chemical compositions were prepared by induction heating in this paper.After normalizing
quenching and tempering
the microstructure was observed by optical microscope and scanning electron microscope
and the mechanical and electromagnetic properties were tested.The results show that the matrix of Fe-Cu alloy is mainly ferrite...
