Role of recrystallization and second phases on mechanical properties of (CoCrFeMnNi)95.2Al3.2Ti1.6 high entropy alloy

The present work reports microstructures and mechanical properties of the homogenized and cold-rolled (CoCrFeMnNi)95.2Al3.2Ti1.6 (at. %) high entropy alloy annealed at various temperatures. The material was cold-rolled and annealed in the temperature range from 600 °C to 1000 °C for 1 h. The σ phase was observed in the annealing temperature range from 600 °C to 800 °C while the B2 phase was observed in the annealing temperature range from 700 °C...
