A comparative study using water atomized and gas atomized powder in laser powder bed fusion process – Assessment of the fatigue performance
Zusammenfassung
Gas-atomized (GA, spherical) and water-atomized (WA, spattered) commercially pure iron (cp-Fe) powders were processed using laser-based powder bed fusion, resulting in a slightly higher porosity of the WA condition. In addition to characterization of quasi-static mechanical properties, fatigue tests, which are known to be detrimentally affected by porosity, were finally considered, revealing good properties even for the WA condition. In terms of microstructure stability, the GA and WA specimens significantly differ; effects seen can be rationalized based on the actual chemical compositions. While the GA specimens show an obvious yield phenomenon and softening under cyclic loading, the WA specimens reveal microstructure stability in cyclic tests.
