The polycrystalline CrMnFeCoNi high-entropy alloy was deformed in tension at temperatures between 4 K and 300 K. Stress – strain curves were taken until fracture. Thermal activation parameters were derived from stress relaxation tests. Moreover, the microstructure and texture development was studied. It is found that the deformation behavior changes characteristically at certain temperatures. This relates to yielding, serrated flow, work-hardening, fracture, microstructure and texture formation. The different deformation mechanisms operating at low temperatures in this advanced metal alloy will be demonstrated and discussed.
