Intership's topic: Corrosion resistance of 2xxx aluminum alloys developed for aerospace application after long exposure at high temperature


For new and future generations of airliners and space launchers, requirements in terms of weight reduction, inspection intervals and aircraft manufacturing costs are particularly high. For several years now, these demands have been driving a major R&D effort in advanced aluminum alloys, and will continue to do so in the future. Constellium, a leading supplier of aluminum solutions, is responding to this challenge by developing new alloys with low density and high mechanical properties.

The resistance of these solutions to various forms of corrosion is one of the criteria determining inspection intervals for aeronautic structures. The in-service temperature of some parts (e.g. engine inlet lip skin) can be between 150 and 250°C. The aim of this internship is to improve our understanding of the corrosion resistance of 2xxx alloys after long exposure at high temperatures. The main tasks of the internship are:

  • Launch and analysis of corrosion tests on various 2xxx alloys after long exposure at different temperatures.
  • Analysis of microstructural evolution by optical microscopy, scanning and transmission electron microscopy, DSC, conductivity... after long exposure at high temperatures.
  • Establish links between corrosion results and microstructural evolutions to better understand the influence of temperature and exposure time on microstructure and corrosion mechanisms in 2xxx alloys.

The internship will take place within the Aerospace R&D team of the Metallurgy unit (MET), in close collaboration with the Corrosion unit (ACS/CORR). The trainee will need to be adaptable in order to work with different teams at the research center, and to master different experimental techniques.
