Among modern structural materials the high entropy alloys (HEAs) and related compositionally complex alloys (CCAs) have aroused great interest within scientific community in the past decades, due to their very promising combination of properties such as strength, ductility, toughness, as well as corrosion, oxidation and wear resistance. In combination with laser based direct energy deposition (DED) technique, these materials can offer new sustainable solutions for applications at elevated temperatures and in harsh environments e.g. in energy and transportation sectors.

In the current study a combinatorial high-throughput screening approach based on CALPHAD simulations and experimental validation has been utilized to explore a (CoFeNi)Cr10AlyTiz CCA-system. This technique allows to perform a rapid alloy development within a wide compositional range and automated fabrication of graded components with varying chemical composition and microstructure. Extended by semi-automated analytical characterization of the produced samples, this approach enables to design novel CCAs with promising properties for specific requirements
