Various tungsten (W) materials doped with potassium (K) and added with rhenium (Re) to improve thermo-mechanical properties have been developed, including K-doped W, W-Re alloys, and K-doped W-Re alloys. In the presentation (2), we will show the effect of potassium doping on thermo-mechanical properties of tungsten.
