Накратко на български

Нови метални сплави се изследват така, че да запазват свойствата си дори при наличие на примеси от рециклиран метал. Това помага за намаляване на въглеродните емисии и разхода на енергия при производството на стомана, алуминий и мед.

Recycling-oriented alloy design for next-generation of sustainable metallic materials

European industry increasingly focuses on recycling to reach carbon neutrality by 2050. Recycling offers enormous energy savings and CO2 reductions; namely 58%, 92% and 65% for steel, aluminium and copper, respectively, compared to primary metals production. However, there are several problems hindering metals recycling such as the progressive accumulation of metallurgical impurities in alloys produced from scrap metal. An effective solution to counter these problems is the development of new alloys, recycling-friendly by design for transition to circular economy supported by European green deal, EuRIC Circular Metals Strategy and other initiatives. Concentrated solid solution alloys, including some of the established alloys, have considerable potential for enhanced tolerance to said compositional deviations. This entails that the alloys’ properties do not significantly change by deviating from the chosen average composition, due to the extended compositional space with desired microstructures. Additionally, they show tolerance to higher impurity levels due to their intrinsically high ductility. These attributes are essential for the next generation of robust, recycling-friendly alloys designed for production from metal scrap as raw material, as compared to older alloys designed for production from metallic ores. The objective of the project is the in-depth evaluation of the consequences of the compositional alterations on the changes induced to the basic mechanical properties and damage tolerance of highly alloyed systems. For such evaluation, new experimental alloys will be prepared. The ultimate goal is the preparation of scrap-compatible metallic materials for sustainable metallurgy. The partitioning effects of alloying and impurity elements will be studied with a special focus on their interactions with the lattice and microstructural defects. The high alloys stainless steel base material will be used due to its promising properties for the purposes of ROAD-SiM and its similarity to other systems. Thus, the obtained knowledge will be generally applicable for a large scale of similar materials

Цел на проекта

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 scrapmetal. Elements such as tin cannot be effectively removed during manufacturing alloys from scrap. Therefore, the nextgeneration of alloys will have be able to tolerate more impurities (therefore inclusions) than current alloys. Such materialsalso have to be more resistant to fracture, due to the potential damage nucleation at inclusions. However, impurities causesignificant changes of properties and induce considerable complexity even in simple alloy systems. Therefore, thedevelopment of the recycling-oriented alloys based on understanding of changes caused by various compositionaldeviations require a significant volume of research.Concentrated solid solution alloys, including some of the established compositions of austenitic steels have the attributesessential for recycling-oriented alloys. They show enhanced tolerance to compositional deviations due to the extendedcompositional 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 ofmechanical properties and damage-tolerance of said materials. Ultimately, scrap-compatible alloys for sustainablemetallurgy will be prepared. Special attention will be placed on the effects of the elemental partitioning and their interactionswith 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.
