Abstract
The results of the experimental study of powder materials of various brands and classes (stainless steel, precision soft and hard magnetic alloys) are presented, the influence of their parameters (particles, fracture, fluidity, bulk density) on the properties of finite additive samples is evaluated. The impact of melting parameters on the porosity of additive samples has been studied.
Supporting agencies: Experimental studies were performed on the equipment of the Center for Collective Use “Composition, Structure and Properties of Structural and Functional Materials” of the NRC “Kurchatov Institute” – CRISM “Prometey” with financial support from the Ministry of Science and Higher Education of the RF, Agreement 13.ЦКП.21.0014 (075-11-2021-068), unique identifier RF–2296.61321X0014. The work was carried out with financial support from the Russian Science Foundation in the direction of “Research by world-class scientific laboratories” (project No 21-73-30019, https://rscf.ru/project/21-73- 30019/) and with the support of scientific and educational world-class center “Russian Arctic: new materials, technologies and research methods”.
