The project is proposing to improve various components of a circular economy in the field of aerospace industry. Aerospace is one of the strategically important fields, in which almost all technologies developments are included, due to its complexity of systems and materials used. The aerospace industry needs to overcome the biggest challenges as it uses a number of very specialized and complex structured materials . This can be interpreted in improved performance, but in the same time the raw material needs, the repair and reuse of products and recycling methodologies became less reliable, with a high impact on environment and technology sustainability. Complex concentrated alloys (CCAd) are multicomponent advanced metallic materials with a wide range of mechanical and physical properties. CCAs are a mixture of four or more elements in high proportion. The multicomponent nature of CCAs, allows for a large flexibility in the choice of elements, properties and life-cycle attributes. - CCAs can be used to replace materials both in critical or non critical applications, at similar performance.
- CCAs can be used for recycling a large amount of products without advanced and time consuming separation methods, by the obtaining after melting of a multicomponent alloy.
- If CCAs are used instead of conventional alloys at the fabrication of parts the repair and reuse stages will be more accessible.
- CCA alloys or composites could also be obtained by controlled combustion synthesis from minerals
Main tasks and partners needed:
1. Critical raw material reduction through the use of CCAs - IMNR
2. Definition of the repair and reuse capability of the CCA products – partner needed
3. The recycling methodologies when using CCAs – partner needed
All type of TRLs are possible within the project framework.
National R&D Institute for Nonferrous and Rare Metals (IMNR), Metal Resource Valorisation Technologies Laboratory, Romania, has a wide and extremely valuable experience in the field of special alloys elaborating by conventional and nonconventional methods such as: induction furnace melting (Al based CCA alloys for military applications, high entropy alloys for aerospace industry, Ti-Zr-Ni-TR multicomponent complex alloys for hydrogen storage, Ti alloys), rapid solidification (amorphous and nanostructured thin films and strips of Al and Ti alloys), electrochemical co-deposition in aqueous media (high entropy alloys, thin films protective coatings Zn-Ni-P, semiconductor thin films Cu-In-Se, Sb-Te), microwave furnace for recycling non-ferrous alloys, lead-less soldering alloys. Understanding, prediction and modeling and optimization of metals and alloys characteristics and the synthesis/recycle technologies. IMNR follows a systematic and integrated theoretical-experimental approach for studying the structure-property correlation for a wide range of metallic materials with significant potential for various industrial applications. The applied research character of the institute results from the achievements in the development of alloys obtaining technologies and product standardization. The institute participated in complex international research projects (FP6, FP7, NATO, and M-era.Net projects) in the field of obtaining of advanced nonferrous alloys and composites. Also, the organization possesses infrastructure and expertise for physical-chemical and structural characterization of metallic materials.
