In recent years, medium-entropy alloys (MEAs) have received significant focus for their innovative microstructure and design concept; they exhibit numerous excellent characteristics, making them ideal for several structural and functional applications. It is essential in materials science and engineering to explore how pressure affects the mechanical features of MEAs. We use ab initio simulations with Vienna ab initio Simulation Packages (VASP) and Molecular Dynamics (MD) with Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) to investigate the dislocation, elastic, and mechanical properties of cubic AlCrNi MEA. Dislocation-related properties include mean square atomic displacement (MSAD), critical resolved shear stress (CRSS), lattice distortion, and yield strength. Initially, numerous physical properties of AlCrNi MEA are determined, including the material's elastic stiffness, elastic moduli, ductility–brittleness, machinability index, Vickers hardness, Kleinman, as well as various anisotropy parameters. Then we investigate how pressure affects these physical properties. The importance of investigating the effect of pressure on the physical characteristics of AlCrNi MEA is highlighted by our simulation results, particularly for high-pressure applications.
