16MnCr5 steel parts were additively manufactured by laser powder bed fusion in order to investigate the effect of microstructure on electromagnetic properties. As process parameters have a direct impact on the obtained microstructure, different conditions were used to manufacture samples on which magnetic and electrical tests were conducted. The obtained results were presented and discussed in terms of density, microstructure and electromagnetic properties. Finally, correlations have been demonstrated between the microstructure and the electromagnetic performances. Lower magnetic and electric properties were obtained with the higher porosity rates at low volume energy density. The microstructural effects were evidenced, through a decrease in magnetic properties with grain orientation, and an improvement with stress relief annealing.

为了研究微观结构对电磁性能的影响，对16MnCr5钢零件进行了激光粉末床熔合工艺的增材制造。由于工艺参数对获得的微观结构有直接影响，因此使用不同的条件来制造对其进行磁和电测试的样品。进行了。提出并讨论了获得的结果，包括密度，微观结构和电磁性能。最后，已经证明了微观结构和电磁性能之间的相关性。在较低的体积能量密度下，较高的孔隙率可获得较低的磁性和电性能。通过沿晶粒取向的磁性能下降和通过应力消除退火的改善，证明了微观结构的影响。
