      abstract     = {The qualification process of the materials and components
                      for the next generation of fusion reactors makes it
                      necessary to expose them to similar service conditions as
                      expected during the service life of the reactor. In the
                      present work, W-Eurofer brazed joints (tungsten block: 8 ×
                      8 × 4 mm; steel block: 8 × 8 × 4 mm; joined to an
                      actively cooled copper heat sink) were exposed to steady
                      state heat loads to study the effect of the thermal fatigue
                      on their microstructure and mechanical integrity. Three
                      different W surface temperatures were tested (400, 500 and
                      600 °C) varying the number of applied cycles (100 and
                      1000). The results allowed identifying a braze temperature
                      of 359 °C as threshold condition under which the brazed
                      joints could be used without deterioration. The increase of
                      the surface temperature deteriorated the mechanical
                      integrity of the joints in comparison to those analyzed
                      after the brazing process and accordingly reduced the
                      refrigeration capabilities.},
