Embodiment 1
[0025] Forging material: TC21, phase transition point 965°C, quantity: 5 pieces, forging size: 250×120×50 Step 1, heat forging at the phase transition point.
[0026] The bar is heated at 40° C. under β and then forged and shaped to obtain a billet 1 with a size of 130×80×210.
[0027] Step 2, heating and forging at the phase transition point.
[0028] The billet 1 was first heated at 40°C under quasi-β for 147 minutes, and kept at 15°C for 25 minutes on the beta to obtain hot billet 2. Hot billet 2 out of the furnace pressing process design forging surface 80 thick upper and lower sides, the deformation of the first pressed side is 10%, flipped 180°, the forging corresponding surface deformation is 17%. Billet 3 is obtained.
[0029] Step two, shaping.
[0030] The square billet 3 is adjusted according to the required size of the drawing, 130×80×210, to obtain a free forging at the transformation point.

Embodiment 2
[0035] Forging material: TC18, phase transition point 880°C, quantity: 10 pieces, forging size: 120×292×577
[0036] Step 1, heating and forging below the phase transition point.
[0037] The bar is heated at 35° C. under β and then forged and shaped to obtain a billet 1 with a size of 160×270×550.
[0038] Step 2, heating and forging at the phase transition point.
[0039] The billet 1 was first heated at 40° C. under the quasi-β for 115 minutes, and kept at 15° C. for 50 minutes on the beta to obtain the hot billet 2 . Hot billet 2 out of the furnace pressing process design forging surface 160 thick upper and lower sides, the deformation of the first pressed side is 8%, flipped 180°, the forging corresponding surface deformation is 15%. Billet 3 is obtained.
[0040] Step two, shaping.
[0041] The billet 3 is adjusted according to the required size of the drawing, 120×292×577, to obtain a free forging at the transformation point.
