Keywords:Fusion reactor, Tungsten, Potassium doping, Mechanical properties, Recrystallization

To improve both mechanical properties and recrystallization resistance, tungsten alloys, which are dispersion-strengthened by potassium bubbles and lanthanum oxide and alloyed by rhenium, have been developed. In the presentation (3), we will show the mechanical properties and recrystallization behavior of potassium-bubble-dispersion-strengthened tungsten-rhenium alloys.
