Al16Co21Cr21Fe21Ni21 high entropy alloy (HEA) offers an interesting microstructure comprising of contiguous hard BCC/B2 high entropy phase rich in Ni and Al intertwined with soft FCC phase rich in Fe, Co and Cr. that exhibits high strength with sufficient ductility in tension at room temperature. In the present investigation, Al16Co21Cr21Fe21Ni21 HEA was cold rolled to 90% thickness reduction at room temperature and the evolution of microstructure and texture was monitored using electron back scatter diffraction and X-ray as well as neutron diffraction respectively. It is observed that there is partitioning of stress and strain between the two phases that leads to a distinct dislocation activity in individual phase which gets translated into a distinct texture evolution. The importance of contiguity and relative strength of FCC and BCC phase on the evolution of microstructure and texture as a function of deformation strain in two phase HEA is discussed.
