| Abstract Scope |
High-entropy alloys (HEAs) exhibit excellent mechanical and thermal performance due to their multi-principal element design. This study investigates the effect of mechanical alloying on the mechanical and thermal properties of a FeCoCuNbMo high-entropy alloy. Equiatomic elemental powders were subjected to high-energy mechanical alloying for different milling durations to achieve solid-solution formation and microstructural refinement. Phase evolution and microstructural changes were examined using X-ray diffraction and electron microscopy, confirming the development of a nanocrystalline solid-solution structure with increasing lattice distortion. Mechanical alloying led to a notable improvement in mechanical properties, particularly hardness, attributed to grain refinement, severe plastic deformation, and solid-solution strengthening. Thermal analysis using differential scanning calorimetry revealed enhanced thermal stability and suppressed phase transformations with prolonged milling. The findings demonstrate that mechanical alloying is an effective route for tailoring the microstructure and enhancing the mechanical and thermal properties of FeCoCuNbMo HEA, highlighting its potential for high-temperature and structural applications. |
