The basic processes of formation of structure of tungsten alloys in investigated intervals of temperatures - recrystallization through a liquid phase and coalescention tungsten grains. In work it is shown, that optimum properties and minimum for the given maintenance of an alloy tungsten alloys with high contents of a sheaf get form distortion at once after occurrence of a liquid phase and keep them before excess of the maintenance of a liquid phase of critical value of 35 % (on volume).
