Ni含量对Fe3Si基合金组织的影响

Effect of Ni Content on the Microstructures of Fe3Si Based Alloy

    摘要
  • 摘要: 通过X射线衍射、能谱、SEM金相等方法,对5种不同Ni含量样品的显微结构进行了分析,结果表明:Ni质量分数为0%的Fe3Si基合金都存在六方结构的含镍富硅Fe2Ti相析出;当Ni质量分数在0%-2%范围内变化时.Ni的添加对富硅Fe2Ti的析出影响很小;而当Ni增加到3%,Ni的添加急剧促进富硅Fe2Ti的析出;当Ni的添加超过一定量(约2%)时就能明显促进Fe3Si基合金的动态再结晶以及静态再结晶.

     

    Abstract: The microstructure of 5 differeent Ni content specimen were studied by XRD.EDX.SEM and opticed microscope. The results show:Fe2Ti phases containing rich Si and Ni precipitate in the Fe3Si based alloy with Ni content ranging from 0%~4%. Ni addition has a little influence on the precipitation as Ni (in mass fraction) is ranging from 0%~2%, Ni addition accelerates the precipitation of Fe2Ti phase in the Fe5Si based alloy with the 3% Ni and the precipitation weakens in the Fe3Si based alloy with the 4% Ni. Ni addition promotes the dynamic recrystallization and static recrystallization as the Ni (mass fraction) is over 2%.
