Abstract
In this work, we studied the structure of the magnetically hard material of the Fe–Cr–Co system manufactured at the Russian SLM FACTORY system by selective laser melting from spherical powder, particles’ size less than 80 μm. The powder was obtained by melt atomization. To study the structure, magnetic and mechanical parameters, samples were made at various scanning speeds and laser power. By constructing a hysteresis loop, data are obtained that indicate a higher level of magnetic characteristics (Br, Bd, Hd, Hcb, Hcm, and BHmax) of the metal of the samples obtained by selective laser melting than similar samples obtained by foundry technology.
Supporting agencies: The work was supported by the Ministry of Education and Science of the Russian Federation (the unique identifier is RFMEFI62519X0046).
