Research description

In current reactor designs for DEMO, tungsten is the most promising candidate material, but brittleness is an important problem. By alloying W with other elements, researchers hope to overcome this issue. Only a few compositions have already been studied experimentally.

The remaining alloys are numerous and there is a high probability that some of them will outperform the best ones currently known. A computational screening method allows to select the most promising candidates, without needing extensive experiments.

The general purpose of this project therefore consists in performing such a study by means of density-functional theory (DFT). For a large set of supercells, representing different doping levels and elements, several properties relevant to the fusion problem are predicted and interpreted.
