Summary
European industry increasingly focusses on recycling, pushing towards circular economy as part of EU Green deal. This offers enormous energy savings and CO2 reductions. However, there are several problems hindering the metals recycling.
Effective solution to counter these problems is the development of new alloys, recycling-friendly by design.
One of the rising problems during recycling, is the progressive accumulation of impurities in alloys produced from scrap
metal. Elements such as tin cannot be effectively removed during manufacturing alloys from scrap. Therefore, the next
generation of alloys will have be able to tolerate more impurities (therefore inclusions) than current alloys. Such materials
also have to be more resistant to fracture, due to the potential damage nucleation at inclusions. However, impurities cause
significant changes of properties and induce considerable complexity even in simple alloy systems. Therefore, the
development of the recycling-oriented alloys based on understanding of changes caused by various compositional
deviations require a significant volume of research.
Concentrated solid solution alloys, including some of the established compositions of austenitic steels have the attributes
essential for recycling-oriented alloys. They show enhanced tolerance to compositional deviations due to the extended
compositional space with desired microstructures. and intrinsically high ductility levels.
In this project, we first aim to analyze the consequences of the compositional changes and impurities to the changes of
mechanical properties and damage-tolerance of said materials. Ultimately, scrap-compatible alloys for sustainable
metallurgy will be prepared. Special attention will be placed on the effects of the elemental partitioning and their interactions
with defects. The project outcomes will contribute to the development of recycling-oriented alloys on the global level, for future green metallurgy with reduced environmental impact.
