Optimization of the Microstructure and Mechanical Properties of AZ31 and 7075 Alloy Welds Produced by FSSW and RFSSW Processes

What if the key to tomorrow’s lightweight and high-performance assemblies lies in the encounter between two alloys with opposite behaviors?
This project explores the still-uncharted frontiers of friction stir welding, where magnesium and aluminum alloys reveal unprecedented potential. After a promising first phase focused on homogeneous joints, the team is now ready to push the process further — rethinking the tool, the machine, and even the microstructure of the weld itself.
At the crossroads of mechanical innovation and metallurgical challenges, this project paves the way for new horizons in hybrid materials and next-generation joining technologies.
