High Entropy Alloys: Breakthrough Materials for Aero Engine Applications?

In this project the current literature regarding a relatively new materials type, high entropy alloys (HEAs), was reviewed to find if they are applicable to aero engines, and in particular the engine parts made by GKN Aero Engine Systems in Trollhattan. To manage this the current state of the art of aero engine materials was reviewed as well, partly via a literature survey and partly via discussions with company specialists at GKN Aero Engine Systems in Trollhattan. Based on these two reviews, several issues requiring further studies for future researchers to fill in the gap was identified, with possible solutions suggested where possible, and finally possible HEA systems were suggested for use in the specific engine parts manufactured by GKN Aero Engine Systems.
