dc.description.abstract | In the present study, high temperature (700-1100 degrees C) tensile deformation behavior of hot-rolled CrMnFeCoNi high-entropy alloy was investigated. A single face-centered cubic phase was retained in the hot deformed specimens under different deformation conditions. The flow behavior was significantly influenced by temperature and microstructure evolution. A strong temperature dependence of yield stress was observed with a drastic drop in yield strength from 413 MPa at 700 degrees C to 94 MPa at 900 degrees C. A profound increase in ductility was observed above 700 degrees C and a perceptive decrease in ductility was observed above 900 degrees C. Electron backscatter diffraction analysis indicates incomplete dynamic recrystallization at 700 degrees C leading to a significant difference in the flow behavior. (C) 2017 Elsevier B.V.
