Abstract

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%.
