Progresses in multi-materials billet manufacturing out of metal scraps through friction stir consolidation
2023
Abstract. The evolution of Friction Stir Consolidation (FSC) from recycling towards upcycling technique proved to be one of the excellent solid-state methods for manufacturing functionally graded billets. Multi-material Functional Graded Materials (FGMs) represent a novel class of materials characterized by a gradual change in properties and functions which can be tailored to enhance components performance. Manufacturing techniques play a critical role in achieving the designed compositional and microstructural distribution. Specifically, FSC allows the manufacturing of FGM billets out of metallic chips; the mixing of different metallic chips offers mutually exclusive mechanical properties …

The team, since the early stages of the project, has worked with the will to seize, in collaboration and multidisciplinary dialogue, an opportunity for cultural and scientific growth to achieve shared solutions. The regeneration of the area subject of this study has assumed four elementary actions as operational tools declined to the urban, architectural and technological scale: include, subtract, add and connect. In Tor Bella Monaca, the lack of sense of urbanity is the real cause of environmental discomfort. The size, the layout and the position of the large residential units deprive the inhabitants of a sense of belonging to the city that has been reformulated by reorganizing the greener…

Polymer mechanical recycling: downcycling or upcycling?
2004
Recycled plastics are considered as materials with physical, mechanical and aesthetic properties worse than the virgin ones. In fact, this is true because degradation during lifetime and during the recycling operations changes the structure and the morphology of the polymers and then the final properties of the secondary material. Several “strategies” are under investigation, and in some cases also applied, in order to avoid further degradation during recycling and, if possible, to repair the macromolecules broken during lifetime and then to restore or to improve the initial properties. In this paper the more important techniques, already used in industry or under investigation, according …
