What is it about?

This research investigates the development of strengthening precipitates in cerium-modified additively manufactured AlSi alloy and examines the applicability of in-situ alloying. Furthermore, for as-built and T6 conditions, precipitates are characterized and hardness response is analysed.

Why is it important?

Cerium-containing precipitates were previously reported to be coarsening resistant, paving the way for Al alloys capable of high service temperature. However, a literature gap exists concerning additive manufacturing of these alloys. This research provides understanding of the printability and precipitate development for Al-Si-Ce alloy system.

Perspectives

This paper lays the groundwork for further exploration and development of 3D printable Al-Si-Ce alloy systems. Such an alloy may be useful for high-value automotive or aerospace applications by providing an alternative to more expensive and heavier alloys for high temperature applications.
