Unfortunately, high-strength aluminum alloys such as AA7075 are prone to hot cracking during PBF-LB/M, as well as welding. Both a large solidification range promoted by the alloying elements zinc and copper and a high thermal gradient accompanied with the manufacturing process conditions lead to or favor hot cracking. In the present study, a simple method for modifying the powder surface with titanium carbide nanoparticles (NPs) as a nucleating agent is aimed. The effect on the microstructure with different amounts of the nucleating agent is shown. For the aluminum alloy 7075 with 2.5 ma% titanium carbide nanoparticles, manufactured via PBF-LB/M, crack-free samples with a refined microstructure having no discernible melt pool boundaries and columnar grains are observed. After using a two-step ageing heat treatment, ultimate tensile strengths up to 465 MPa and an 8.9% elongation at break are achieved. Furthermore, it is demonstrated that not all nanoparticles used remain in the melt pool during PBF-LB/M. author: - first_name: Steffen full_name: Heiland, Steffen id: '77250' last_name: Heiland - first_name: Benjamin full_name: Milkereit, Benjamin last_name: Milkereit - first_name: Kay-Peter full_name: Hoyer, Kay-Peter last_name: Hoyer - first_name: Evgeny full_name: Zhuravlev, Evgeny last_name: Zhuravlev - first_name: Olaf full_name: Keßler, Olaf last_name: Keßler - first_name: Mirko full_name: Schaper, Mirko last_name: Schaper citation: ama: Heiland S, Milkereit B, Hoyer K-P, Zhuravlev E, Keßler O, Schaper M.
