The invention relates to a sintering technique of a tungsten-titanium alloy and belongs to the technical field of alloy preparation. The sintering technique comprises the following steps that 1, raw materials are mixed and comprise tungsten powder, titanium hydride, zirconium hydride and strontium oxide, then a PVA aqueous solution is added to conduct water-based ball mill, and the ball mill timeis 2-5 h; 2, mixed powder is loaded into a mold, the pressure of 200-400 MPa is exerted to the mixed powder to enable the mixed powder to be formed, and thus a formed blank is obtained; 3, the formedblank is sintered under protection of argon in a high-temperature vacuum furnace, the sintering temperature is 1800-2000 DEG C, and heat-preservation sintering is conducted for 2-5 h after the furnaceinterior temperature reaches the sintering temperature; and 4, after high-temperature sintering is conducted, cooling is conducted till the temperature is minus 60 DEG C-minus 90 DEG C, the temperature is kept, and a longitudinal magnetic field is exerted for treatment for 100-150 min.
