Beschreibung

Motivation

Additive Manufacturing (AM) allows the production of parts with complex geometries that are unattainable with conventional manufacturing processes. Laser powder bed fusion (LPBF) is particularly relevant for constructing strong, lightweight metal parts. However, standard metals for lightweight applications, such as aluminum (Al), are only printable in a certain processing window and thus not well suited for these applications.

Next to process design, material design is a key factor in overcoming this issue. Microalloying Al with other metals, such as titanium (Ti) and zirconium (Zr), can influence the microstructures developing during the solidification, making the alloy usable for LPBF.

 

In a previous project, we could find key characteristics of Ti-microalloying and pointed out the main obstacles to overcome. With this knowledge, we want to verify and extend our findings.

 

Goal

This Thesis aims to analyze the influence of adding different metals to aluminum in varying quantities on the nucleation process, the resulting crystal structures, and material propterties after solidification.
