      abstract     = {Microstructure induced by plastic deformation at 600 °C in
                      as-fabricated and recrystallized tungsten grades of ITER
                      specification is studied by means of transmission electron
                      microscopy (TEM). Both grades are produced by AG Plansee and
                      being used by fusion community as research material for
                      plasma facing and high heat flux components. Reference
                      microstructure was investigated by a combination of TEM,
                      scanning electron microscopy and nano-indentation
                      techniques. TEM was applied to investigate the necking
                      region in the tensile samples deformed up to ~ $30\%$ of
                      stain. The deformation-induced microstructure was
                      characterized and compared for the two grades in terms of
                      the dislocation density, heterogeneity, observation of
                      pile-ups and tangles specifically near high angle grain
                      boundaries. The obtained evolution of the dislocation
                      density was compared with the prediction of the previously
                      developed thermo-mechanical model for the plastic
                      deformation of polycrystalline tungsten and a good agreement
                      was found without modification of the original parameter
