Friction Stir Welding of Innovative High Strength Aluminium Alloys
As the world’s second most widely used metal (after iron), aluminium (Al) and its alloys play a crucial role in decarbonizing the transportation sector
and achieving climate neutrality for both the EU and our world. Essentially, Al-alloys reinforced with quasicrystalline (QC) phases have the potential
to be used as the main structural material in e-vehicles due to their strength, lightness, corrosion resistance, recyclability and formability. However,
during the joining process of larger parts, the realised temperature may affect the microstructure and mechanical properties due to the strong flow of
the material and the transformation of intermetallic phases. In this project, the process parameters of friction stir welding will be defined to obtain
high-quality joints.
A passion for creating impact
The successful implementation of the optimized FSW process for high-strength aluminum alloys could revolutionize manufacturing processes and enable the production of lighter and more energy-efficient vehicles. This is in line with the broader societal goals of reducing emissions and improving the sustainability of the transportation sector.

Interdisciplinary approach
The project is closely linked to several research disciplines, such as: Chemistry, Economic Sciences, Information Science and
Engineering and Physics.
Why FSW?
By using the FSW technique, a high-quality joint can be achieved while preserving the quasicrystalline structure.
Scientific impact
Understanding the complex material movement, temperature distribution and plastic deformation of advanced joining solutions for next-generation materials.
Societal impact
The proposed solution, which leads to higher mechanical properties, will have an impact on a better quality of life and a lower environmental impact.
Economic impact
The potential for widespread adoption in key industries suggests a significant contribution to both economic growth and environmental progress.
Knowledge transfer
The interplay between industry, research institutions and academia—drives innovation, economic growth, and societal progress by fostering collaboration, accelerating knowledge transfer, and enhancing workforce preparedness.
