Effect of temperature and strain rate on the deformation behaviour and microstructure of Al0.7CoCrFeNi high entropy alloy

The high-temperature deformation behaviour of Al0.7CoCrFeNi alloy was studied at 800–1100 °C and 0.01–10 s−1. The alloy exhibited extensive softening via recrystallization and recovery with the examined temperature and strain rate domains. The recrystallization mechanism in the FCC phase was geometr...
