TL;DR: In this paper, the stacking fault energy of paramagnetic FeCrCoNiMn high entropy alloy is investigated as a function of temperature via ab initio calculations, and the results explain the recently reported twinning observed below room temperature and predict the occurrence of the hexagonal phase at cryogenic conditions.

TL;DR: The authors show that twinning can be a primary deformation mechanism in three well-known medium- and high-entropy alloys that have unstable face-centered cubic lattices.

TL;DR: In this paper, an extended twinning nucleation Peierls-Nabarro (P-N) model was used to predict the twinning critical resolved shear stress (CRSS) of face-centered cubic (FCC) CrCoNi-based MHEAs.

TL;DR: In this paper, the magnetic properties of FeCrCoNiAlx high entropy alloys were investigated using Monte-Carlo simulations and first-principles alloy theory and showed that face-centered-cubic structures possess significantly different magnetic behaviors uncovering that the alloy's Curie temperature is controlled by the stability of the Alinduced single phase or fcc-bcc dual phase.

TL;DR: In this paper, first-principle alloy theory was used to determine the Curie t of the magnetic state near room temperature, which is very promising for several technological, including magnetocaloric applications.
