The alloy has good hot working performance, with forging heating temperature of 1140 ℃ and final forging temperature of 950 ℃
2
The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging
3
Argon arc welding can be carried out for the alloy in the solid solution state, and it shall be treated in time after welding to eliminate the welding stress
4
Surface treatment process: the machined parts shall be electropolished
If mechanical polishing is adopted, the final polishing wear mark shall be consistent with the length direction of the blade
5
The heating speed of solid solution treatment of parts should not be too fast, and stepped heating curve can be adopted
