      abstract     = {In future fusion power plants, plasma-facing materials for
                      the first wall of the reactor have to withstand extreme
                      conditions combining long-term stability during regular
                      operation and suppressed oxidation in the case of an
                      accident. Self-passivating metal alloys with reduced
                      thermo-oxidation (SMART) are promising candidates. Based on
                      tungsten as matrix material, the alloys contain chromium as
                      passivating element and yttrium as active element. Recently,
                      it has been shown that submicron grain sizes led to the best
                      oxidation resistance. Processing of such kind of materials
                      is challenging. Here, field assisted sintering
                      technology/spark plasma sintering (FAST/SPS) of mechanically
                      alloyed tungsten, chromium and yttrium powders was applied
                      to produce submicron grained SMART materials with
                      homogeneous microstructure and well-balanced properties.
                      Main factors influencing the processing of SMART materials
                      via FAST/SPS are discussed and first attempts to scale up
                      the technology (100 x 100 mm2) are presented. Finally,
                      oxidation resistance under accident conditions was
                      investigated.},
