Tungsten titanium niobium carbonitride solid solution powder
The invention belongs to the field of new material preparation, and specifically provides a tungsten titanium niobium carbonitride solid solution powder preparation method, which comprises: uniformly mixing 25-30 parts by weight of titanium dioxide, 10-13 parts by weight of tungsten carbide, 12-20 parts by weight of niobium oxide, 20-25 parts by weight of titanium nitride, and 15-20 parts by weight of carbon black, carbonizing the mixed material for 2-3 h at a temperature of 2000-2200 DEG C in a high temperature horizontal carbon tube furnace, cooling to obtain a block-like tungsten titanium niobium carbonitride solid solution, and then carrying out ball milling to obtain the single-phase tungsten titanium niobium carbonitride solid solution powder with the Fsss particle size of 1.5-4 [mu]m. With the tungsten titanium niobium carbonitride solid solution powder of the present invention, the high temperature resistance of the hard ally can be increased, and the fracture toughness of the hard ally can be increased.
