Processing and Properties of Nanocrystalline CoCrFeNiCuAlTiXVMo High Entropy Alloys by Mechanical Alloying

摘要

Fabrication of nanocrystalline equiatomic high entropy alloys is a crucial aspect for the product of many tools. The present study describes the synthesis of nanocrystalline equiatomic CoCrFeNiCuAlTiXVMo (X?=?Zn, Mn) high entropy alloys by mechanical alloying and their characterization by XRD and SEM. The CoCrFeNiCuAlTiXVMo (X?=?Zn, Mn) high entropy alloys have BCC solid solution with crystallite size less than 10?nm. These alloys are stable even after annealing at 600°C for 1?h. The hardness of the high entropy alloys is found to be 7.6 and 6.2?GPa, respectively.
