Abstract
The evolution of density of tungsten sheets with different dopant content is studied. The microstructure evolution and annealing behavior of three kinds of tungsten sheets with deformation of 63, 83, 92%, are studied. The results show that when rolling deformation reaches to 92%, the density of lanthanum-doped tungsten sheets increases from 18.4 to 18.9 g/cm3, and the density of Potassium-doped tungsten sheets increases from 17.6 to 19.15 g/cm3. The deformation of lanthanum oxide particles increases with the increment of deformation, and the tungsten sheets exhibit a typical rolling state. The microstructure of doped tungsten sheets at high temperature is more stable than that of the pure tungsten ones.
