Abstract

A high-entropy FeCoNiCrMn alloy with a single face-centered cubic phase was synthesized and subsequently annealed at different temperatures to systematically investigate the grain growth behavior. It was observed that the growth kinetics could be described by a power law of 3 and the activation energy for growth was about 321.7 kJ mol-1. The hardness of the alloys was measured as a function of grain size, and the result was found to follow the classical Hall-Petch strengthening, though with a relatively high hardening coefficient.
