The current state-of-the-art suggests that high-entropy alloys (HEAs) will pave the way for high-performance manufactured goods through extraordinary material properties and unique combinations of properties.While this new class of alloy has already been the topic of intense scientific work and basic research and huge scientific advances, HEAs are still not manufactured and applied at industrial scale.

This overview lecture will start with a short introduction to the basic definition, classification and applica-tion potential of HEAs. It continues by identifying the main prevailing barriers and challenges on the way to applications, such as for instance the nearly infinite compositional space or the complex and restricted processbility. Based on that overview the contribution will than highlight the current status of applied HEA-related research with respect to alloy design, fabrication and application relevant performance with particular emphasis on mechanical properties as well as oxidation, corrosion and wear resistance. Finally, recommendations for future trends, needs and the industrial implementation of HEAs in in industrial sectors such as aerospace, power generation and tooling industry will be discussed
