| 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Fe2Si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Fe2Si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 all- oy 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 pro- motes the dynamic recrystallization and static recrystallization as the Ni (mass fraction) is over 2%. |
