Embodiment 1
[0028] 1. Ingredients: According to the composition of Ti-3.5wt% Fe-4.0wt% Al-0.02wt% Gr alloy, zero-grade sponge Ti, industrial pure iron, pure aluminum and graphene are prepared respectively; the purity of the metals is ≥99.99%.
[0029] 2. Melting: Vacuum suspension casting method is adopted. During smelting, control the vacuum degree in the furnace to ≤10 -2 Pa, the furnace temperature is 1600°C, and the alloy ingot is prepared. After sufficient cooling, peel the ingot to remove the outer oxide layer.
[0030] 3. Annealing treatment: Annealing treatment is carried out in a box-type resistance furnace, the annealing temperature is 970-990°C, the holding time is 1h, and air-cooled.
[0031] 4. Extrusion treatment: Extrusion temperature: 850-900°C, extrusion ratio greater than 16, extrusion speed 4-6mm / s; pipe pre-stretching deformation 3%, and finally finished.
