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 (1), we will show the mechanical properties and recrystallization behavior of tungsten alloyed by rhenium.
