Thermodynamic and Ab Initio Design of Multicomponent Alloys Based on (FeMnCoCr)-xBx (x = 0, 5, 7, 10, and 15 at.%).

Multicomponent alloys have attained general interest in recent years due to their remarkable performance. Non-equiatomic alloys with boron addition as an interstitial element are being studied, exhibiting outstanding mechanical properties. In order to estimate the mechanical behavior of potential alloys, thermodynamic and ab initio calculations were utilized in this work to investigate phase stability and stacking fault energy (SFE) for (FeMnCoCr)-xBx (x = 0, 5, 7, 10, and 15 at.
