Tungsten is the front-runner candidate for building the plasma-facing armour components for future fusion reactors. However, in-service irradiation by fusion-neutrons and helium will create lattice-defects in the material, compromising its properties and lifetime. Improving the component's resilience to radiation damage and accurately …

We alloy our tungsten with rhenium to obtain greater ductility and a lower brittle-to-ductile transition temperature. In addition, tungsten-rhenium also has a higher recrystallization temperature and better creep resistance. We use the WRe standard compositions – WRe05 and WRe26 – as a thermoelement material in applications up to over 2000 °C.
