This contribution presents the research conducted on Selective Laser Melting (SLM) of high-silicon steel (6.9%wt.Si). The relationship between the laser processing and the microstructure of the printed alloy was firstly investigated through the use of various microscopy and spectroscopy techniques with the ultimate aim of printing near-fully dense parts. The evolution of the microstructure, including stress relaxation, homogenization, grain growth, solid state precipitation of intermetallics and crystallographic texture was then studied as a function of various ad-hoc heat treatments to understand how to augment the mechanical and quasi-static magnetic properties of the printed parts. This research shows how additive manufacture, combined with a suitable annealing post heat treatment, can lead to the realisation of parts of novel functional design and properties that compare favourably with those reported for commercial silicon steel laminations.
