      abstract     = {High-Entropy Alloys (HEAs) are alloys with at least four
                      principal elements in (near-)equiatomic proportion, which
                      crystallize on simple crystal lattices, such as face-centred
                      cubic, bodycentred cubic, or hexagonal close-packed. These
                      alloys have a stoichiometrically random distribution of
                      constituent elements on all available lattice sites, and
                      they formsingle-phase solid solutions with perfect
                      topological order and complete chemical disorder. The
                      structural simplicity of HEAs makes them well-suited to
                      address fundamental scientific issues related to
                      structure-property relationships. In this work, the
                      plasticity of two HEAs, face-centred cubic CrMnFeCoNi and
                      body-centred cubic TiVZrNbHf, was investigated through
                      uniaxial deformation experiments on single crystalline
                      CrMnFeCoNi and polycrystalline TiVZrNbHf samples. The
                      thermodynamic activation parameters of the reformation
                      process were determined, andmicrostructural investigations
                      were carried out on both alloys using transmission electron
                      microscopy. These investigations revealed the underlying
                      deformation mechanisms of both alloys. Although both alloys
                      deformthrough the slip of dislocations on characteristic
                      slip systems, CrMnFeCoNi behaves like a conventional
                      face-centred cubic alloy with exceptional strength, while
                      TiVZrNbHf exhibits a yield stress anomaly that is unique to
                      HEAs.},
