Abstract
The cryogenic plastic deformation of CrCoFeMnNi high entropy alloy is characterized by three distinct stages based on the change of the work hardening rate. Microstructure and bulk texture at different strain levels were studied by electron backscatter diffraction (EBSD) and neutron diffraction. Our findings indicate that the dislocation slip evolved in the entire deformation, while the formation of deformation twins led to constant work hardening rate at Stage II and resulted in the appearance of close-by <115> component in the loading direction in inverse pole figure (IPF). The twinning-mediated tensile plastic deformation finally induced the strong {111}<112> texture component and minor {001}<110> texture component accompanied with twinning-induced {115}<552> texture component.
