Abstract: Fe-Si composite is widely used in motor core manufacturing because of its excellent magnetic properties and low material cost. Selective electron beam melting (SEBM) is an additive manufacturing technology with high preheating temperature, high energy utilization rate, high power density, and low residual stress, which is especially suitable for direct forming of refractory and brittle metal materials. The effects of linear energy density (E) on the microstructure, texture and magnetic properties of Fe-3.5wt%Si alloy by SEBM were investigated. The results show that the powder gradually melts completely with the increase of E, and the defects of the printing process such as pores and unmelted powder are wea-kened, and the porosity is reduced to less than 1% when E is greater than 180 J/m. Grain size is highly correlated with energy input. With the increase of E, the average grain size of the sample first increases and then decreases. The reason for the decrease of grain size is that the high energy input leads to the intensification of Marangoni effect and the increase of nucleation site, and the average grain size reaches the maximum of 161 μm when E=180 J/m. Parallel to the building direction (BD), the columnar crystals grow significantly. When E=140 J/m, perpendicular to the BD direction forms a cubic texture ({100}〈001〉) with an intensity of 4.71. With the increase of E, the texture strength of λ fiber decreases, and the preferred orientation gradually shifts from {100} plane to {110} plane. The coercivity (Hc) of the sample is negatively correlated with the grain size. Hc decreases first and then increases with the increase of E. When E=180 J/m, that is, when the average grain size is maximum, Hc reaches the minimum value of 1.07 Oe.
