Abstract:
The printing of Fe-6.5wt%Si by LB-PBF is a complex process due to the formation of brittle phases during processing, which can lead to sensitivity to internal stresses. The paper shall show the issues encountered during processing and the resulting material, based on optical microscopy, defect analysis and classification. The manufacturing of thin walls has yielded better results than thick bulk material, and various laser melting strategies will be presented to demonstrate the trend between single and multiple meltpool thicknesses. The internal grain texture of the wall is obtained by means of EBSD. Furthermore, the magnetic hysteresis cycle of the printed material is measured using a vibrating magnetometer.
