• Micro-alloyed Al-rich Al-Co-Cr-Fe-Ni-Ti HESA (HESA-3A) exhibited attractive blend of strength, resistance to coarsening, and resilience against oxidation • HESA-3A exhibited high volume fraction of γ′-phase (>64%) and elevated γ′-dissolution temperature (>1180 °C) • HESA-3A exhibited low coarsening rate of 2.8 * 10−28 m3/s at 800 °C. • Al-rich HESAs displayed an activation energy of ~220 kJ/mol for oxidation.Publication classification
