Mechanical performance of (NbTaW)1−xMox (x = 0, 0.05, 0.15, 0.25) refractory high entropy alloys: Perspective from experiments and first principles calculations

NbMoTaW refractory high entropy alloy (RHEA) possesses superior high temperature mechanical strength while the very low plastic strain at room temperature limits its practical applications. In present work, the method of adjusting composition was employed to improve the mechanical properties of (NbTaW)1−xMox (x = 0, 0.05, 0.15, 0.25) alloys especially the plasticity at room temperature by the combination of experiments and first-principles...
