Fig. 3

a The typical uniaxial true stress-strain curves of our EHEAs. b The curves of strain hardening rate versus strain for the EHEAs. The inset shows the enlarged region marked by the red rectangular. c The fracture morphologies observed on the AC and P2 EHEA samples (left panel: the plan view of the sample surface next to the fractured surface; right panel: the plan view of the fracture surfaces). d Comparison of our Al18Co30Cr11Fe11Ni30 EHEAs to single-phased, dual-phased M/HEAs and EHEAs in the Al-Co-Cr-Fe-Ni family with regards to their strength and ductility.
