What is it about?
High-entropy alloys have found a niche in radiation damage resistance, and hence, have triggered the interest in the use as materials for advanced reactors. This interest is sometimes induced by preconceptions which lack basis in science, one of such preconceptions is that the high value of configurational entropy would imply a high stability of simple solid solutions. We show in the present work that this does not happen in the present HEA.

Why is it important?
Providing a strong scientific base for understanding the irradiation damage resistance of HEAs allow for the better design of ideal materials for this application. The present case, for example, shows that the alloy decomposes and that nanoprecipitates of FeCo with strong magnetic properties are formed. This decomposition, however, is not entirely prejudicial since if could be used to produce nanomagnets is an efficient way
Perspectives
This is another work produced by Dr Matheus A Tunes, one of my most prolific collaborators. He is surely one of the most important researchers in the field, in spite of his young age. This work was granted a back cover in the issue in which it was published.
