Strength–ductility synergy at ambient and cryogenic temperatures via Cu-precipitation-tuned stacking fault energy in a Fe–Cr–Ni–Mn–Mo–Cu alloy

Key Points

• Strength and ductility synergistically improved in the alloy due to Cu precipitation, enhancing performance.
• Key metrics include a notable increase in ductility by 25% at cryogenic temperatures compared to ambient conditions.
• Observational analysis reveals a unique relationship between stacking fault energy and precipitation in the alloy composition.
• Findings highlight promising material behavior at varied temperatures, but may require real-world validation.
