Abstract of the dataset | To obtain a successful product during additive manufacturing, the powder as a raw material must have the high quality. The purpose of this work is to investigate CrMnNi steel powders obtained by inert gas atomization with nickel content: 3, 6, and 9 wt% and to identify dependencies between the powder size and morphology, solidification structure, and change in chemical composition and thermophysical properties. Particle size distribution is measured by a laser scattering analyzer: d50 value are 82.02, 69.32, and 75.54 μm for powders with 3, 6, and 9 wt%, respectively. Surface tension (ST) measurements are made by maximum bubble pressure method: for steels with 3, 6, and 9 wt% at temperature 1500 °C, ST is 1.01, 1.07, and 1.15 mNm 1, respectively. It is found that the change in particle size affects the chemical composition, the content of the ferromagnetic phase and secondary dendritic arm-spacing. Changes in the content of elements such as S, O, N, and Mn are determined, depending on the diameter of the particles. The influence of changes in content of S, O, and N on the thermophysical properties such as ST is investigated. | |

Project abstract | The focus of this project is to investigate the interaction of a Al-killed low-sulphur manganese-boron steel and a highly basic desulphurisation slag with MgO-C products based on recyclates and environmentally friendly binders. In order to determine the influence of thermophysical properties on the interaction with new refractory materials, the viscosity, surface tension and density of the liquid aluminium-killed steel in undesulphurised and desulphurised condition and the slags with high sulphur capacity are investigated as a function of [S], [B], (SiO2), (MgO), (S) and temperature. By finger testing a MgO-C product in the molten steel and slag, the refractory samples are obtained for further analysis of the interactions using optical microscopy and SEM/EDX. The (S)/[S] distribution between the MBW1500 steel and the slag is investigated in a crucible of MgO-C products based on recyclates in the MFG-40. The inclusion population of the steel samples after examination via Finger Testing is interpreted by chemical analysis and analysed by optical examination methods such as light microscopy combined with AFA (Automatic Feature Analysis) in P-SEM. The spinel formation between recycled MgO-C material and liquid steel is specifically studied in SEM/EDX microscopy. | |
