摘要：

The consolidated results of studies of tungsten doping with various metals and compounds (Ni, Fe, Cu, Mo, Y2O3, La2O3) are presented, the advantages of doping with regard to its conditions, microwave and plasma sintering techniques are shown. It has been found that the mechanical properties of tungsten are significantly improved by the addition of the above elements. The resulting heavy fame tungsten can be used to protect against nuclear radiation.
