High entropy alloys (HEAs) and medium entropy alloys (MEAs) have been increasingly attracting attention because of their unique mechanical and thermal properties. Adding precipitates to HEA and MEA matrices is a way of improving the materials’ strength further. In addition to the materials strength, adding precipitates has been shown to affect the phase transformation of the matrix. Understanding the role of precipitate characteristics, such as volume fraction and interparticle spacing, on the phase transformation and mechanical behavior is critical for the development of design principles for improving the materials’ mechanical behavior. In this work, using molecular dynamics simulations we investigate the role of precipitates in deformation and phase transformation of HEA/MEAs, and compare the results to experimental observations.
