• High-entropy alloys exhibit superior strength-ductility synergy due to severe lattice distortion and sluggish diffusion effects.
• Tailoring elemental composition and processing parameters enables precise control over microstructural evolution, leading to enhanced mechanical properties.
• Advanced characterization techniques and computational modeling are crucial for predicting phase stability and accelerating alloy design.
• Scalable manufacturing and environmental sustainability remain key challenges for the widespread adoption of HEAs in industrial applications.
