Complex concentrated alloys, encompass high entropy alloys (HEAs), provide a unique opportunity to study the fundamental dislocation science in a compositionally complex alloy systems. Microstructurally simple alloy systems were chosen to investigate the effect of severe lattice distortion on dislocation plasticity in HEAs. Alloys with varying chemical composition were synthesized to maximize the intrinsic lattice distortional strain. To understand the dislocation plasticity, both rate sensitivity of the flow stress and activation volume of dislocations were evaluated as a function of lattice distortional strain and temperature. Furthermore, thermomechanical processing techniques were employed to tailor the microstructural features such as grain size and twin density, and the properties were subsequently examined.
