Size-dependent tensile behavior of nanocrystalline HfNbTaTiZr high-entropy alloy: Roles of solid-solution and local chemical order

Key Points

• Tensile behavior varies significantly with size, affecting material strength and ductility.
• The maximum tensile strength observed at a specific size was 1.2 GPa, highlighting size dependence.
• Observational analysis of samples varying in size was conducted to understand solid-solution effects.
• Understanding these size effects aids in optimizing high-entropy alloy applications and advancing material design.
