Fig. 3: Optimal alloys for high yield strength.

From: Computational discovery of ultra-strong, stable, and lightweight refractory multi-principal element alloys. Part II: comprehensive ternary design and validation

Fig. 3

Yield strength versus temperature for select ternary compositions that maximize YS a–c when metastable with respect to phase separation and d–f in phase equilibrium over three temperature ranges. Experimental (E) data for CrMoNbV16 (metastable) and MoNbTaVW8 (equilibrium) are included for reference. Solid and dashed lines in (d–f) are YS model predictions for single- and dual-phase BCC solid solutions, respectively.
