Abstract

The evolution of microstructure and texture during hot deformation was investigated in an equiatomic multicomponent CoCrFeMnNi alloy. For this purpose the alloy was obtained in the cast form and thermos-mechanically processed toobtain a wrought microstructure with average grain size of ~ 28 μm. Hot compression samples were subsequently extracted from this alloy. The hot compression tests were carried out at temperatures ranging from 700°C to 1000°C and strain rates varying from 0.001/s to 1/s. The flow curves were analyzed for understanding the deformation behavior. The microstructure and texture evolution was investigated using electron backscatter diffraction system.
