Deformation mechanisms of Al0.1CoCrFeNi at elevated temperatures

Deformation mechanisms of a high-entropy alloy with a single face-centered-cubic phase, Al0.1CoCrFeNi, at elevated temperatures are studied to explore the high temperature performances of high-entropy alloys. Tensile tests at a strain rate of 10−4 s−1 are performed at different temperatures ranging from 25 to 700 °C. While both yield strength and ultimate tensile strength decrease with increasing temperature, the maximum elongation to fracture...
