Lightweight refractory high-entropy alloys (LRHEAs) have received significant attention due to their excellent strength-plasticity matching. Generally, its strengthening mechanism mainly comes from solid solution strengthening caused by atomic radius mismatches, but excessive atomic radius mismatch...
