摘要：
The new soft magnetic material based on the permalloy powder was successfully used for a three dimensional sample fabrication via selective laser melting process. The microstructures of the Fe-80%Ni-alloy samples as a function of the laser influence parameters were studied by optical and scanning electron microscopes equipped with energy-dispersive microanalysis, X-ray diffraction and micro hardness measurements. The effects of external magnetic fields (EMF) on the growing structures during the laser melting were estimated. The reduction in coherent-scattering regions of magnetic phases under SLM with EMF is accompanied by the coercivity growth. (C) 2016 Elsevier B.V. All rights reserved.
