Complex Metallic Alloys: New metallic materials !

Today:
Metals-based industries today rely largely on materials based on elementary metals and binary metallic alloys to which a number of additional elements are added in smaller quantities to tailor them for particular properties.
Structure of a complex metallic alloy

CMAs:

Complex metallic alloys are formed with crystal structures based on giant unit cells containing many tens, up to more than a thousand atoms per cell. As a result, these materials can offer unique combinations of properties, which are excluded in conventional materials.

Therefore, the scientific programme of CMA consists of fundamental approaches such as the calculation of the electronic properties of compounds, the research into ternary and quaternary phase diagrams, structure-property relations combining sophisticated structure determination techniques with advanced techniques like photo-electron spectroscopy and X-ray emission and absorption spectroscopy.

These items provide input for computer modelling. This enables the Network to develop strategies to improve the materials properties towards certain goals. For the Complex Metallic Alloys, such a goal is the tuning of a particular electronic structure which is at the origin of the particular hybrid properties leading to new multi-functional materials derived from them.
