【摘要】 本文研究了具有较低热膨胀系数的Ｆｅ－Ｎｉ和Ｆｅ－Ｎｉ－Ｃｏ合金的磁性和磁性温度稳定性。研究发现，Ｆｅ－Ｎｉ系的两种合金的μｍ均随温度升高而增加，但是在Ｆｅ－Ｎｉ－Ｃｏ合金中，由于合金成分的不同，μｍ随温度的变化趋势也不同。另外，本文还研究了不同含量的微量元素Ｃｕ对磁性和磁性温度稳定性的影响。更多还原

【Abstract】 Mgnetism and the temperature stability of magnetism of FeNi and FeNiCo alloys with low thermal expansion coefficient are studiedIt is found that μm of FeNi alloys incresses with the increase of temperature.But in FeNiCo alloys, with differences of their compositins,the changes of μm differ from one another when the temperature changes.In addition,the effect of Cu content on magnetism and the temperature tability of magnetism is also studied.更多还原
