The Advanced and Nanostructured Materials Laboratory addresses both scientific research directions (fundamental character) and technological and technical research directions (applicative character).
The specific strategic objective of this laboratory is the development of high value added advanced and nanostructured materials, based on non-ferrous metals, for medical applications, energy and extreme work conditions.
Scientific objectives involve focusing on the following main types of activities:
- Synthesis and efficient fabrication of advanced and nanostructured materials through environment-friendly methods, intelligent integration of new and existing processes to ensure efficient transfer of knowledge to industrial innovation;
- New fundamental products that provide sustainable solutions in the field of medicine, energy and extreme working conditions;
- Advanced scientific knowledge on the potential impact of advanced and nanostructured materials on health or the environment and identifying the tools needed to assess the risk over the lifetime;
- Developing the ability to measure / characterize the properties of advanced and nanostructured non-ferrous metal materials and the predictive modeling of their manufacturing processes to allow their rapid introduction to the market.
The laboratory has an extensive experience in the field of special alloys elaborating by conventional and nonconventional methods.
The main expertise of the research group is based on the obtaining of metals and alloys (Al-Cr-Cu-Fe-Mn-Ni-Ti multi-component high-entropy alloys, Ti-Zr-Ni-TR complex alloys for hydrogen storage, Ti alloys) by the melting and casting route (electrical and induction furnace melting) and heat treatment. Also, ANM has valuable expertise in the synthesis of metallic materials through mechanical alloying (Al-Mg-Mn-Cr-Ti alloys), rapid solidification (amorphous and nanostructured thin films and strips of Al and Ti alloys) and electrochemical co-deposition in molten salts (Al-TR, Al-Li, Mg-Nd, Pb-Ca, Nd-Fe), ionic liquids (Al-Cr-Cu-Fe-Mn-Ni high entropy alloys) and in aqueous media (thin films protective coatings Zn-Ni-P, semiconductor thin films Cu-In-Se).
The fundamental scientific research is focused on the theoretical understanding, prediction and modeling and optimization of metals and alloys characteristics and the synthesis technologies. ANM 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 department activity results from achievements in the development of innovative alloys obtaining technologies and product standardization and commercialization. The laboratory has participated in complex national and international research projects in the field of advanced nonferrous alloys.
