Your mission : Optimize structure of process route using spin forming for Space application

Aluminium is a key player in Space application as it offers low density and high performances. Spin forming is one the of the possible method to shape the domes of the launchers. The complete process route must be optimized to reach the targeted microstructure with this new process, especially for big pieces requiring pre-welding by FSW. Abnormal grain growth can indeed be present in some conditions.

This internship will focus on 2xxx alloys used in Space application. The study aims to optimize the process route to master the final structure after complete process, through lab scale simulation of industrial process. The impact of process schedule on final grain structure will be analyzed.

The goals is to propose strategies to better control microstructural evolution and improve alloy performance.

The project will contain multiple steps :

• Bibliographical survey
• Define best simulation routes at lab scale
• Follow the transformation of products at the lab-scale
• Characterize the microstructure through optical observations
• Build a comprehensive database
• Analyze the data, use models and draw conclusions to make concrete suggestions on methods to further optimize process

The intern will work within the metallurgy team and will be supervised by two R&D engineers.
