| Popis: | “Top-quality powder is a precondition for additive manufacturing of quality components.” This paper covers the powder characterization of high-melting and highly reactive intermetallic γ-TiAl powders by combining technological and metallographic examinations. Measurements of tap density, bulk density, flow behaviour, particle size distribution and sphericity of the powder will reveal characteristic parameters which have an effect on process stability. The subsequent analysis of the powder microstructure will show possible gas inclusions or defects which may negatively affect the mechanical properties of the manufactured component. Each of these factors presents a quality criterion, which is also applicable – irrespective of the alloy system – to other materials systems. |
