Beschreibung

Initial situation

At the Professorship of Laser-based Additive Manufacturing, the research team focuses on advancing laser- and powder bed-based additive manufacturing processes. Powder bed fusion using a laser beam (PBF-LB/M) enables the production of highly complex, functionally optimized metallic components with unprecedented design freedom.     
Nickel-based superalloys such as Inconel 738 are of particular interest for high-temperature aerospace and energy applications due to their excellent creep resistance and mechanical strength. However, their processing via PBF-LB/M remains challenging because of their susceptibility to cracking and the complex solidification behavior during laser melting.

Aim and content of the work

The aim of the thesis is to identify and evaluate a suitable process window for PBF-LB/M processing of Inconel 738 using advanced beam shaping and laser oscillation strategies. Building on existing internal experiments, the microstructure shall be tailored to improve mechanical properties by adjusting the laser-material interaction and thermal history.

The following work packages (WP) form the content of the thesis:

WP1: Literature review on PBF‑LB/M of nickel‑based superalloys, laser beam shaping, and oscillation strategies

WP2: Analysis of existing internal experiments and definition of process parameter windows

WP3: Experimental manufacturing of samples using selected process windows

WP4: Microstructural characterization (e.g., metallography, porosity analysis)

WP5: Evaluation of microstructure-property relationships and derivation of optimization measures

WP6: Documentation and presentation of results
