Abstract Scope Different selective laser melting (SLM) processes were carried out to produce Fe-6.5 wt% Si soft magnetic alloy samples. The corresponding macro characteristics, microstructure and texture were characterized. The samples prepared under the condition of low energy density have larger densities of porosity and defects. The as-printed Fe-6.5 wt% Si alloy has weak texture, coarse grains in the top-view section and columnar grains in the side-view section. After annealing at 800-1000 °C, the grain growth was not significant, and the textures were slightly weakened. After increasing the annealing temperature to 1100 ºC, abnormal grain growth occurred, which may be related to the low stored energy and initial size advantage before annealing.
