The high entropy alloy Al0.65CoCrFe2Ni has been developed using a vacuum arc melting furnace followed by copper suction casting. The XRD analysis has confirmed the presence of both FCC and BCC phases. The presence of both the phases improves the balance of strength and ductility of the material. Split Hopkinson pressure bar test has been carried out at different strain rates under compressive loading to understand the dynamic deformation behavior of the dual phase high entropy alloy. The deformation mechanisms under a range of strain rates are analyzed to understand the strain hardening nature and strain rate sensitivity of the material. The possibility of evolution of substructures associated with high strain rate loading, such as twins, dislocation entangling etc., is also investigated. The predictability of high strain rate behavior of the high entropy alloy will also be examined using Johnson Cook (J-C) constitutive modeling.
