Embodiment 1
[0024] Step 1, put tungsten powder with a particle size of 6-8 μm into the planetary high-energy ball mill tank, add 5% alcohol as a dispersant, add WC balls at a ball-to-material ratio of 15:1, and then pre-pump the ball mill tank Nitrogen is filled after the vacuum, the speed of the ball mill is 400r / min, and the ball milling time is 6h;
[0025] Step 2, mix the ball-milled tungsten powder and Ti powder evenly on a V-shaped mixer;
[0026] Step 3, put the mixed powder into the discharge plasma sintering furnace, start heating when the vacuum reaches 6Pa, raise the temperature to 1300°C at a heating rate of 100°C / s and keep it for 10 minutes, then cool down with the furnace, and the fine powder can be obtained in a short time. Crystalline tungsten-titanium alloy.
[0027] The fine-grained tungsten-titanium alloy obtained in Example 1 was wire-cut and machined to prepare a metallographic sample, and the microstructure was observed by a scanning electron microscope. It was fou...
