Direct-casting induced micro-cellular segregation and supranano precipitates enhance strength-ductility in Co-free medium-entropy alloys

Key Points

• Enhanced strength and ductility achieved through micro-cellular segregation and supranano precipitates.
• A significant increase in mechanical properties, with improvements noted in both strength and ductility metrics.
• Direct casting methods were used to promote micro-cellular segregation, resulting in innovative alloy structure.
• Findings suggest potential applications in structural materials, but further studies are essential for detailed validation.
