Effect of interstitial N atom on physical and mechanical properties of FeCoCrNiMn high-entropy alloys: A first-principles study

The physical and mechanical properties can be greatly affected by lattice distortion caused by interstitial atoms. However, at nanoscale, effect of interstitial atom on high entropy alloys (HEAs) still requires to be discussed. Here, we study effect of interstitial N atom on formation energy, lattice constant, elastic modulus, density of states, and deformation charge density in FeCoCrNiMn HEAs using first-principles calculation. The results...
