specific Embodiment approach 1
[0013] Specific embodiment one: In this embodiment, a method of introducing hydrogen to improve the forging performance of γ-TiAl alloy is carried out according to the following steps:
[0014] 1. Use mechanical processing to remove the oxide layer on the surface of the γ-TiAl alloy and wash it with acetone for 3 to 5 times, then place it in the tubular hydrogen furnace, and evacuate the tube hydrogen furnace to an absolute pressure of 1×10 -3 Pa, then fill in high-purity argon until the relative pressure in the tubular hydrogen furnace is -0.04MPa~-0.02MPa, and then feed hydrogen at a temperature of 700°C~800°C, and the partial pressure is 0.05 MPa~0.15MPa, keep warm for 2h~4h, cool to room temperature with the furnace, and finally obtain the hydrogenated γ-TiAl alloy blank A; the hydrogen atomic percentage in the hydrogenated γ-TiAl alloy blank A is 0.2%~1%;
[0015] 2. Spray the high-temperature antioxidant on the surface of the hydrogenated γ-TiAl alloy billet A obtained i...
specific Embodiment approach 2
[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the atomic percentage of hydrogen in the γ-TiAl alloy blank A described in step 1 is 0.4%-0.9%. Others are the same as the first embodiment.
specific Embodiment approach 3
[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the atomic percentage of hydrogen in the γ-TiAl alloy blank A described in step 1 is 0.6%. Others are the same as those in Embodiment 1 or 2.
