abstract
The thermal shock resistance of spark plasma sintered tungsten grades, containing between 0.25 weight% and 1 weight% yttrium, are investigated under fusion relevant ELM-like loading conditions. The tungsten samples were cyclic tested at room temperature using a Nd:YAG laser beam and the electron beam facility JUDITH 1. Heat pulses with durations of 1 ms were applied to the samples leading to absorbed power densities between 0.37 GW/m and 1.14 GW/m². Furthermore, at a temperature of 400 °C, three samples were tested with the highest power density of 1.14 GW/m². The characterization of samples before and after exposure shows that the thermal shock resistance improves with increasing yttrium content. However, in contrast to pure tungsten, there is still brittle behavior for the yttrium-doped tungsten at the base temperature of 400°C.
