Fine regulation of sigma phase achieves excellent mechanical properties in Co-free CrFeNiSi0.2 medium entropy alloy

Fine regulation of sigma phase achieves excellent mechanical properties in Co-free CrFeNiSi0.2 medium entropy alloy

The balance between strength and plasticity is the ultimate objective in the exploration of alloy design. This study focuses on achieving synergy between strength and toughness in the CrFeNiSi0.2 medium entropy alloy through various heat treatments to regulate the size and morphology of the σ phase....
