Keywords:Fusion reactor, Tungsten, Oxide-dispersion-strengthening, 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 (2), we will show mechanical properties and recrystallization behavior of oxide-dispersion-strengthened tungsten-rhenium alloys.
