High Entropy Alloys2 have been identified as a possible replacement for superalloys in propulsion systems’ components due to their inherent high specific strength and oxidation resistance at high temperatures.
HEAs are a relatively new class of materials, and although since 2004 more than 600 HEA journal and conference papers have been published, the whole HEA world is still dealing with numerous unanswered questions. Therefore, in order to exploit these advancements on HEA, further work is needed.
