Resumo

The results of a study of the structure and properties of additive medium carbon steel Fe–0.45C–0.4Si–0.7Mn–0.1V–0.3Mo–0.2Cu–1Cr–1.5Ni (in % by weight) alloyed with tungsten in an amount from 1 to 10% by weight are presented. The possibility of tungsten alloying of steel during additive manufacturing was studied. The alloy was carried out when mixing the powders of armored steel and tungsten, then mixture was selective laser melted. It was confirned that during the medium-carbon steel alloying with a different amount of tungsten, both density and hardness change non-linear. The results of the study can be useful for new materials developing and optimizing the laser powder bed fusion.
