| Abstract Scope |
High-Entropy Alloys (HEAs) are single-phase-disordered solid solution alloys with multiple principal elements. HEAs present superior thermodynamic stability and mechanical properties, which lead to the potential applications in structural, aerospace and energy industries. In this work, we present a molecular dynamics model to simulate the mechanical and tribological properties of AlCoCrFe HEA coating on aluminum substrate. Using the simulated nanoindentation and tribology tests, the Young’s modulus and coefficient of friction of the HEA are derived. Compared to pure aluminum substrate, HEA coating demonstrates a higher Young’s modulus and a lower coefficient of friction, which is consistent with experimental observation. |
