Tailoring the microstructure and mechanical properties of (CrMnFeCoNi)100-xCx high-entropy alloys: Machine learning, experimental validation, and mathematical modeling

•Microstrucutre and mechanical properties of interstitial-containing HEAs during cold rolling and annealing were characterized.•Effects of processing parameters and chemical composition on the recrystallization and grain growth behaviors of (CrMnFeCoNi)100-xCx HEAs were quantified.•Grain size, carbide precipitation, and tensile yield stress for the model (CrMnFeCoNi)100-xCx HEAs were modeled.•Machine learning models, mathematical relationships, and equations for the contribution of each strengthening mechanism were proposed and verified by experimental work.
