Abstract [en]

The flowability of a powder is an important characteristic that depends on both the physical properties of the particle ensemble and the testing method, equipment and conditions. In additive manufacturing processes, flowability can be an indicator of the quality of the deposited powder layer and, therefore, the final component. In this study, we carried out a comparison of the flowability of different steel powders and the data generated by a range of testing methods. Each sample had a unique combination of composition and particle size range. Flowability testing equipment and methods were selected according to standards (angle of repose, Hausner Ratio, Hall flow) or published literature (FT4 Powder Rheometer). We measured the flowability of different samples for each testing method, in order to obtain a first dataset. Secondly, we evaluated the correlations between different flowability testing methods.
