摘 要：<正>Fe—Ni alloy,as a widely applied ferromagnetic material,is synthesized using selective laser melting（SLM）.The chemical compositions and microstructure of the SLM Fe—Ni alloy are characterized by X-ray diffraction（XRD）, energy dispersive X-ray spectroscopy and scanning electron microscopy.It was found that the samples exhibited fine grains with homogenous distribution when a low laser scanning velocity was used.Moreover,the magnetic properties of the samples with different laser parameters are also measured.It shows that the SLM Fe—30%Ni alloy possesses a low coercivity and high saturation magnetization.It also can be obtained that SLM is an alternative faster method to prepare soft magnetic material with complex shapes.Moreover,the magnetic properties can be influenced by the laser parameters.
