Structure and magnetic properties of the material of the Fe–Cr–Co system produced by the selective laser melting

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 ( B r , B d , H d , H cb , H cm , and BH max ) of the metal of the samples obtained by selective laser melting than similar samples obtained by foundry technology.
