PROJECT TITLE: « Development of new aluminum alloys for Laser Powder Bed Fusion additive manufacturing technology (LPBF) »

In June 2020, Constellium C-TEC launched the new AHEADDTM activity of commercializing aluminum powders for additive manufacturing.

This internship will focus on the development of new aluminum alloys for the LPBF application with the aim of expanding the current AHEADDTM product portfolio.

New innovative compositions will be designed and prototyped as powders for LPBF technology using a new pilot atomizer. Samples will be printed from each batch of powder by an LPBF printing partner and will then be characterized at C-TEC.

This characterization will include a characterization of the internal health of the samples by optical microscopy and SEM (porosity, cracks, microstructure) and a mechanical characterization: hardness, tensile tests, fatigue and creep for the most promising alloys.

The effect of post-fabrication heat treatment on the microstructure and mechanical properties will also be studied during this internship.

The candidate will participate in identifying new compositions to be tested based on the results obtained during the first iterations. Finally, a detailed bibliographic study will be carried out to position the microstructures and mechanical performances obtained on our alloys in relation to literature data.

Education level: Master’s student or final year undegraduate

Engineering school in metallurgy or material science

Competencies & technical & soft skills requirement:

Teamwork
Autonomy
Scientific rigor
Curiosity
Taking initiative
Good level of the English language (both written and spoken) French language would be a plus
