      abstract     = {This study focuses on a quantitative analysis of
                      dislocation accumulation after cold plastic deformation and
                      mechanical properties of FeNiCoCrMn and TiNbHfTaZr high
                      entropy alloys (HEAs) which are single phase fcc and bcc
                      solid solutions, respectively. In order to study the role of
                      compositional complexity from unary to quinary compositions
                      on dislocation accumulation and mechanical properties after
                      plastic deformation, the single solid solution phase forming
                      sub-alloys of the two HEAs were investigated. All studied
                      samples revealed a large plastic deformability under
                      cold-rotary swaging process by $85–90\%$ area reduction
                      without intermediate annealing. The dislocation density of
                      all studied samples, determined by Williamson-Hall method on
                      synchrotron X-ray diffraction patterns, were between
                      10$^{14}$ - 10$^{15}$ m$^{-2}$ dependent on the alloy
                      composition. The level of dislocation density after plastic
                      deformation is not only affected by the number of
                      constituent element but the lattice distortion and intrinsic
                      properties in terms of stacking fault energy, modulus
                      misfit, and melting point also impact the dislocation
                      storage. The level of dislocation density determines the
                      level of mechanical properties because of a resistance to
                      dislocation motions. The hardness and yield compressive
                      strength of the studied samples are proportional to the
                      level of dislocation density.},
