Tuning the mechanical behavior of high-entropy alloys via controlling cooling rates

The microstructures determine the macro-mechanical properties in metals and alloys. However, the formation mechanism of microstructures in high-entropy alloys (HEAs) rapidly cooled to room temperature still remains unknown at nanoscale. Here, we present the AlCoCrCuFeNi HEAs prepared by various cooling rates and the deformation behaviour using molecular dynamic simulation. The results show that the radial distribution function of HEAs is in good...
