Main research activities/topics/projects

The main advantage of using metallic materials such as aluminum alloys is the possibility of recycling and reuse. Aluminum production involves a costly and environmentally impactful manufacturing chain: mining and production of Al2O3 to obtain aluminum. This manufacturing chain is responsible for one of the most important industries in the world: the aeronautical industry. The development of aircraft-grade aluminum alloys, such as the 7xxx series for example, was responsible for the increase in the size of aircraft. However, the number of retired aircraft has increased and, according to AFRA (Aircraft Fleet Recycling Association), around 15,000 aircraft will be retired in the next two decades. This is an opportunity to develop new processes to revalue and reuse disassembled parts. It is an opportunity to remanufacture them for a new application, to produce powder by atomizing aluminum gas. 

This research proposal to be carried out in the laboratories of the Politecnico di Torino, involving the Brazilian postdoctoral fellow, aims to investigate the microstructure and mechanical properties of AA 7075 obtained by gas atomizing scraps to manufacture lattice structures by laser powder bed fusion. These powders will be fully characterized, evaluating their chemical, physical and processing properties.
