                      fine-grained, recrystallized (TFGR)-W to tokamak edge plasma
                      environment, two TFGR-W specimens (TFGR-W $1.1wt\%TiC$ and
                      TFGR-W $3.3wt\%TaC)$ were exposed to 31 identical ohmic
                      discharges in the TEXTOR tokamak by means of a limiter lock
                      system. The highest surface temperature reached was about
                      1300 °C. Under these temperature conditions, the bulk
                      microstructure and dispersoids distribution of both TFGR-W
                      remained intact, suggesting that these TFGR-W tungsten
                      materials have sufficient stability under these plasma
                      loading conditions. The erosion of TiC dispersoids on the
                      surface was enhanced by plasma exposure above 1150 °C,
                      while such enhanced erosion was not observed for TaC
                      dispersoids probably due to the higher melting temperature
                      of Ta than Ti.},
