Cross-scale heterogeneity enables strengthening and strain de-localization in a FeMnCoCr multi-principal element alloy

Key Points

• Enhanced strain localization occurs due to cross-scale heterogeneity, promoting better material performance.
• Research reveals phase transformations and strengthening mechanisms in the FeMnCoCr alloy model.
• Comprehensive analysis across multiple scales uncovers critical interactions within the alloy's structure.
• Significance lies in potential applications for advanced materials in engineering and manufacturing sectors.
