Abstract

The multicomponent L12 phase in high entropy alloys (HEAs) has shown excellent thermal stability. However, the understanding of its intrinsic origins is limited to the Lifshitz-Slyozov-Wagner (LSW) theory. In the present study, we investigate the influence of lattice misfit, which is not considered in LSW theory, on the coarsening kinetics of the multicomponent L12 phase. Different from that in most traditional alloys, the coarsening constant of multicomponent L12 particles decreases with the increasing lattice misfit in HEAs. This finding provides a new view for understanding the sluggish coarsening kinetics of L12 phase in HEAs.
