      abstract     = {The microstructural and mechanical characterization of an
                      equiatomic YGdTbDyHo high entropy alloy with hexagonal
                      close-packed structure was performed. The phase state and
                      chemical homogeneity of the solid solution were analysed
                      with respect to crystal structure, phase stability, and
                      oxide formation. It was found that Y-rich precipitates form
                      at grain boundaries and that the alloy is prone to
                      oxidation, leading to a homogeneous distribution of
                      ∼10 nm-sized oxides in the grain interiors. The plastic
                      response at the sub-grain level was studied in terms of the
                      activated slip systems, critical resolved shear stresses
                      (CRSS), and strain hardening using micropillar compression
                      tests. We observe plastic slip on the basal <a> system, with
                      a CRSS of 196 ± 14.7 MPa. Particle strengthening and
                      strength dependence on sample size are discussed on the
                      basis of dislocation particle interaction and mechanical
                      size effects.},
