To improve both mechanical properties and recrystallization resistance, tungsten alloys, which are disperson-strengthened by potassium bubbles and lanthanum oxide and alloyed by rhenium, have been developed. In the presentation (4), we will show the damage formation behavior of dispersion-strengthened tungsten alloys by thermal shock loads.
