Essay

Dissertational work is devoted to pressing question of studying of structure shaping regularity and physicomechanical properties of large-sized preparations from heavy alloys of tungsten with the high contents of a sheaf (W-Ni-Fe). In result it was possible to investigate regularity of sintering large-sized (weight over 10 kg) preparations from a heavy alloy of tungsten with the high contents of a sheaf and to receive a material with high durability (Rm> 950 MPa) and plasticity (?> 20 %).
