It is well-known that grain coaresening due to the recrystallization casuses the embrittlement in tungsten (W) materials. Various W plates doped with potassium (K) and added with rhenium (Re) have been developed to suppress the recrystallization. We will present recrystallization behavior of hot-rolled tungsten plates by high-temperature thermal history
